12-gon

From GeoGebraWiki

Demonstration of how to create a Regular Polygon with 12 sides.

A sequence of Regular_Polygons (4-gon, 5-gon, ...) can be produced by gradually adding more sides.

The Regular Polygon with 12 sides is a dodecagon (12-gon). It has 9 more sides than a 3-gon.

The polygon in the dynamic worksheet can be

• re-sized
• re-oriented
• re-located

by dragging three special points (A, Y and O).

A slider is provided for adjusting the number of sides and thus displaying different Regular_Polygons (3-gon, 4-gon, ..., 12-gon).
