### Geometric examples

**NOTE: ***The images shown on this page are only images!
If you want to access the corresponding applets just click "EXAMPLE
i", \(i=
1,2,3,4,5,6,7,8\) or the corresponding image.*

**WARNING:**
**Sometimes applets take too long to load. If the waiting time exceeds 30 seconds it is advisable to close all windows of your browser and try to connect
again.**

**NOTE:** In the applets handling, you will notice that when a curve leaves the viewport area (black rectangle) it will appear on
the opposite side, as if the opposite sides were glued (as a consequence, the space where the curves are being plotted can be seen as a torus).

EXAMPLE 1: Construction of regular polygons. We can choose the number of sides as well as their lengths through the arrows (green bars with movable button)

EXAMPLE 2: Construction of a set of regular polygons that result from rotation by an angle whose magnitude is tuned by means of a cursor.

EXAMPLE 3: Construction of a set of regular polygons resulting from each other by homotheties. These homotheties have their center in one of the vertices of the polygon and ratio controlled by a parameter that can be changed by a cursor.

EXAMPLE 4: Construction of curious polygonal images.

EXAMPLE 5: "Endless" constructions formed by polygonal lines.

EXAMPLE 6: Construction of images formed by dots or polygonal lines.

EXAMPLE 7: Construction of circles and circular arcs.

EXAMPLE 8: Construction of images consisting of circles and circular arcs.
