Geometric Tools Library 1.0. The motivation for Geometric Tools was my graduate studies in medical image processing; it was then named MAGIC Software (My Alternate Graphics and Image Code). When I entered the 3D video game industry, I spent less time on image code and more time on graphics, physics and mathematics code. Shapes Tool O twice. The tool for creating geometric shapes in paint.net is the Shapes Tool. This new tool replaces the Rectangle, Rounded Rectangle, Ellipse and the Freeform Shape tools found in paint.net 3.5x. The Shape Tool has 29 predefined shapes. 8 Basic shapes, 8 Polygon or Star shapes, 4 Arrows, 4 Callout shapes and 5 Symbols. Preset Shapes. OmniGeometry is designed to generate geometric formations based on recursive geometrical shapes. Everything in OmniGeometry is based on layers and their parameters. Each layer contains over 40 parameters that you can edit, and instantly see the changes in the formation.
Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines, circles or other points. After some construction is done, one can move the points one started with and see how the construction changes.
History[edit]
The earliest IGS was the Geometric Supposer, which was developed in the early 1980s.[1] This was soon followed by Cabri in 1986 and The Geometer's Sketchpad.
Comparison[edit]
There are three main types of computer environments for studying school geometry: supposers[vague], dynamic geometry environments (DGEs) and Logo-based programs.[2] Most are DGEs: software that allows the user to manipulate ('drag') the geometric object into different shapes or positions. The main example of a supposer is the Geometric Supposer, which does not have draggable objects, but allows students to study pre-defined shapes. Nearly all of the following programs are DGEs. For a related, comparative physical example of these algorithms, see Lenart Sphere.

Also, it now[when?] supports macros, line segments, calculations, arbitrary functions, plots, etc. Full documentation is available online.
Dr Genius[edit]
Dr Genius was an attempt to merge Dr. Geo and the Genius calculator.
Dr. Geo[edit]
Dr. Geo[1] is a GPL interactive software intended for younger students (7-15). The later version, Dr. Geo II,[3] is a complete rewrite of Dr. Geo, for the Squeak/Smalltalk environment.
It can be used for entertainment and to educate. The whole concept is to display a series of images, that when they are put together with the first images, will show the transition from one image to the other.In a morphing series of two faces, the middle image will look incredibly life-like, as a real person, but one can easily see it is neither the person in the first or second image. The image in the middle is half influenced by the left and half influenced by the right image.It will cost you a lot less to purchase and use Morphing software than complex animation software. Morphing software programs are used regularly to create special effects for music videos, television commercials and movies.Image morphing is used to compute a transformation, a metamorphosis, from one image to another. Best morphing software. This procedure is called 'morph'.
GCLC[edit]
GCLC[4] is a dynamic geometry tool for visualizing and teaching geometry, and for producing mathematical illustrations. In GCLC, figures are described rather than drawn. This approach stresses the fact that geometrical constructions are abstract, formal procedures and not figures. A concrete figure can be generated on the basis of the abstract description. There are several output formats, including LaTeX, LaTeX/PStricks, LaTeX/Tikz, SVG and PostScript. There is a built-in geometry theorem prover (based on the area method). GCLC is available for Windows and Linux. WinGCLC is a Windows version of GCLC with a graphical interface that provides a range of additional functionalities.
GeoGebra[edit]
GeoGebra is software that combines geometry, algebra and calculus for mathematics education in schools and universities. It is available free of charge for non-commercial users.[5]
GeoKone.NET[edit]
GeoKone.NET[6] is an interactive recursive natural geometry (or 'sacred geometry') generator that runs in a web browser. GeoKone allows the user to create geometric figures using naturalistic rules of recursive copying, such as the Golden ratio.
Geolog[edit]
Geolog[7] is a logic programming language for finitary geometric logic.
Geometry Expressions[edit]
Geometry Expressions[8] Does symbolic geometry. It uses real symbolic inputs and returns real and symbolic outputs. It emphasises use with a Computer Algebra System (CAS), as well as exporting and sharing via interactive HTML5, Lua, and OS X dashboard widget apps.

Geomview[edit]Continuity versus determinism[edit]
All these programs can be divided into two category: deterministic and continuous.GeoGebra can be deterministic or continuous (one can change it in preferences).
All constructions in the deterministic programs (GSP, Cabri, Kseg and most of others) are completely determined by the given points but the result of some constructions can jump or behave unexpectedly when a given point is moved.
On the contrary, some constructions in continuous programs (so far only Cinderella and GeoGebra), depend on the number of hidden parameters and in such a way that moving a given point produces a continuous motion of the construction, as a result, if the point is moved back to the original position the result of construction might be different.
Here is a test to check whether a particular program is continuous:
Construct the orthocenter of triangle and three midpoints (say A', B' C' ) between vertices and orthocenter.
Construct a circumcircle of A'B'C' .
This is the nine-point circle, it intersects each side of the original triangle at two points: the base of altitude and midpoint. Construct an intersection of one side with the circle at midpoint now move opposite vertex of the original triangle, if the constructed point does not move when base of altitude moves through it that probably means that your program is continuous.
Although it is possible to make a deterministic program which behaves continuously in this and similar simple examples, in general it can be proved that no program can be continuous and deterministic at the same time.[17]

I am looking for a program to create images of very simple situations, e.g. this. I have already tried Geogebra but I am not quite satisfied with the result. I want my images to look as if they were taken from some (geometry) book; this is what I mean:
Geometric Shapes Worksheets
This was taken from my last year's geometry lecture notes. I feel like everyone is using the same program to create such images (because they all look the same).
Does anyone know what program I could use in order to create such images? I'm sure I could succeed with both MS Paint and Adobe Photoshop, but I'm looking for some program made to create such images. I hope this is the right place to ask for this and thanks for any help in advance.

If you do not like coding and looking for WYIWYG, then Ipe is a good option.
If you like coding, then you have many options: PSTricks, TIKZ/PGF, Metapost, Asymptote, ..

You may want to try Tikz. See http://www.texample.net/tikz/ for examples.

I use Omnigraffle for the Mac. It is by far the easiest figure-maker for mathematics and is LaTeX friendly. Simply drag and drop predefined shapes (including points, lines, polygons, etc.) within Omigraffle, adjust them as needed for size, opacity, color, etc., use LaTeXIt to add labels or equations, save, then export to pdf or eps. I created the following faithful reproduction of your image by sight in 45 seconds.

You might also try out DrGeo which is a interactive geometry program.

I have been enjoying kseg. It is very quick to draw diagrams in
kseg .
After you draw the diagram you can drag the components around and the others will follow, retaining the same constraints. For example, in this diagram it appears that $NM$ is the perpendicular bisector of $PQ$:
And I can see if that still appears to be the case even after I move point $C$ to make a very different inscribed quadrilateral:
