Worksheet: The Sum of Central Angles
In this worksheet, we will practice identifying central angles and finding their measures using their portion of the circle and their sum.
How many angles are in a circle?
How many turns are needed to make a complete turn?
How many angles does it take to make a full turn?
Bassem turns one-third of a full turn. How many degrees is this?
This circle is divided into 3 equal parts. What is the angle of each part?
What is the value of the central angle of a circular sector when a circular segment and a circular sector have the same area?
, , and are three points on a circle with radius 54 cm and center . The point is the intersection of and and we have and . Find the central angle of the major circular segment giving the answer to the nearest second.
