Circumscribed Polygon

This Circumscribed Polygon assessment also includes:

Trigonometry teachers often go off on a tangent, and here's a worksheet that proves it! First, young mathematicians use a formula with tangent to prove a formula correct for area. Then, they draw conclusions about the area of a circle based on an analysis of their own work.

Instructional Ideas

  • After the worksheet, discuss how mathematicians first discovered the formula for the area of a circle
  • Extend the lesson by also testing it for a triangle
