## Application of a Circle: Angles and Arcs

#### Activity Overview

Students use the properties of circles, angles, and arcs to help design a courtyard with a star-shaped design.

#### Key Steps

• Visit MathNspired.com for additional Action Consequence activities and information.

Students will see an example of how circles can be used to solve a real-world application. Students will use the properties of circles, angles, and arcs to help design a courtyard with a star-shaped design.

• Students will identify the difference between central angles and inscribed angles and identify the relationships between the measures of inscribed angles and the arcs they intercept.

As a result of this lesson, students will use circle concepts, such as diameter, radius, circumference, and area, to determine basic information needed to construct the courtyard.
