In this lesson, we will learn how to identify a central angle in a circle and find its measure using its properties.

Students will be able to

understand what a central angle in a circle is,
find the measure of a central angle given its proportion of the whole angle of the circle,
find the measure of a central angle given the length of the arc that subtends it and the circumference of the circle,
find the measure of a central angle contained in a triangle using the total angle sum of the triangle.
