Perspective Drawing in GeoGebra

You can use GeoGebra to make perspective drawings.

Perspective drawing usually consists of points, lines, segments and polygons as has been described in other entries. In these instructions, we are going to look at a small example you can follow that will help you practice making perspective drawings all by yourself. It’s recommended that you turn on the gridlines in Graphics View if they are turned off.

Example 1

Drawing Eye Level Perspective

Open Graphics View under GeoGebra icon View in GeoGebra icon Menu.
Draw a horizon line in the middle of the coordinate system by using the Line GeoGebra icon tool. Take a look at the figure below for an example.
Draw the vanishing point on the horizon line by using the Point GeoGebra icon tool.
Draw a rectangle by using the Polygon GeoGebra icon tool.
Draw straight lines from the vertices (corners) of the rectangle to the vanishing point by using the Segment GeoGebra icon tool. To make lines dashed, click on Move GeoGebra icon, then click on the line, then click on Style Bar GeoGebra icon in the upper right corner, then click on the second button, and finally select the dashed style.
Then, draw a rectangle inside the first rectangle by using the Polygon GeoGebra icon tool again.
