Theorems Of Circles. Chapter 10 Mr. Mills. Sum of Central Angles. The sum of the measures of the central agles of a circle with no interior points in common is 360 degrees. Draw circle p with radii PA, PB, PC. The sum of the measures of angles APB, BPC, CPA is 360 degrees. Congruent Arcs.
RM = 8
XP = 3
RX = 12
XP = 5
If RM is congruent to ST , XP is 8, and XM is 6.
Tell why the measure of angle CAM is 28 degrees.
Hint: Think SSS.
Hint: The sum of interior angles of a triangle is 180 degrees.
