10.5 Apply Other Angle Relationships in Circles +JMJ
Geometry Notes Name ________________ 10.5 Apply Other Angle Relationships in Circles Recall …. You know that the measure of a central angle ______________ its intercepted arc. You know that the measure of an inscribed angle is ______________ of its intercepted arc.
ANGLES ON THE CIRCLE THEOREM
If a tangent and a chord intersect at a point on a circle, then the measure of each angle formed is one half the measure of its intercepted arc.
!1 intercepts arc ________ m!1 =__________________ !2 intercepts arc _________ m!2=__________________
1. m!1 = ______
2. mAB! =_______
ANGLES INSIDE THE CIRCLE THEOREM
If two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
!1 intercepts arcs ________________ m!1 =__________________ !2 intercepts arcs _______ m!2=_________________
3. x =_______
