Chapter 10.6: More Angle- Arc Theorems

Congruent Inscribed and Tangent- Chord Angles

Theorem 89:    If two inscribed or tangent- chord angles intercept the same arc, then they are congruent. 

Theorem 90:    If two inscribed or tangent- chord angles intercept congruent arcs, then they are congruent. 

Angels Inscribed in Semicircles

Theorem 91:    An angle inscribed in a semicircle is a right angle.

A Special Theorem about Tangent- Tangent Angles

In this picture, the measure of <P + the measure of arcAB = 180⁰ 

Theorem 92:    The sum of the measures of a tangent- tangent angle and its minor arc is 180^o

That’s what we learned yesterday, paired with homework assignment 5:

10.6:    8, 9, 11, 15- 17, 24

10.7:    5, 7, 9, 10, 12, 15, 21
