REGULAR POLYGONS AND CIRCLES
INTRODUCTION

This unit is based on the study of the properties of regular polygons, their basic characteristics and the concept of the circle as a regular polygon with an infinite number of sides.

As this unit is aimed at students in their first and second years of secondary education the content is at a very basic, purely constructive level. 

AIMS
  • To introduce the concept of regular polygons.

  • To work out the perimeter and area of a regular polygon.

  • To construct circles from polygons. 

  • To introduce angles in polygons and circles and how to measure them.

  • To work out the approximate value of p .
