In this lesson we are going to talk about angles and arcs. The first angle we'll talk about is the central angle. That is an angle whose vertex is at the center of a circle. The sum of the measures of the central angles of a circle all adjacent to each other is 360 degrees. You are going to learn the difference between a minor and major arc. Also, you'll learn about arc measures - the measure of the minor arc and the measure of the major arc. This lesson also covers arc length, concentric circles and some important postulates.
*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
