In this lesson, we will learn how to use cyclic quadrilateral properties to find missing angles and identify whether a quadrilateral is cyclic or not.

Lesson Plan

Students will be able to

identify the supplementary angles in a cyclic quadrilateral,
use the supplementary angles in a cyclic quadrilateral to solve problems including equations,
solve problems using the equality of the measure of an exterior angle of a cyclic quadrilateral and the measure of the interior angle at the opposite vertex,
identify when a quadrilateral is cyclic using the summation of two opposite angles,
identify when a quadrilateral is cyclic using the equality of the measure of an exterior angle and the measure of the interior angle at the opposite vertex.
