Constructing Regular Polygons

Activity Overview

Constructing regular polygons

Before the Activity

Students will: 1.Construct an equilateral triangle, a square and a regular pentagon using rotations 2.Measure sides and angles to visualize equilateral and equiangular properties 3.Extend the principles to a polygon with any number of sides

During the Activity

Explore relationships (including congruence and similarity) among classes of two- and three-dimensional geometric objects, make and test conjectures about them, and solve problems involving them. This activity will help students visualize the construction of regular polygons and conceptualize equilateral properties through measurement and movement of their construction. Extension questions are built into the activity.

After the Activity

Review student answers:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
