You can use GeoGebra
to draw points, lines, and planar figures like polygons, circles, and ellipses. You’ll also learn how you can compute the perimeter/circumference and area of your figures.

for lines. Here you’ll find many alternatives to Line
The second tool in the list is Segment
, which lets you draw a line segment between two existing points.
The third tool in the list lets you draw a line segment with a given length.

If your figure is a polygon, follow Item 2.
If your figure is a circle or an ellipse, you can read their separate entries to learn how to draw them: Entry about circles, Entry about ellipses.

Perimeter(<Polygon>)
if your figure is a polygon. Replace <Polygon>
with the name of the figure you got in Step 2.
Circumference(<Conic>)
if your figure is a circle or an ellipse. Replace <Conic>
with the name of the figure you got in Step 2.
Press Enter
. The perimeter/circumference of the figure will be displayed in Algebra View
