Inscribed Angles• Inscribed angles have a vertex on the
circle and sides contain chords of the circle.

Theorem 9-7• The measure of an inscribed angle is
equal to half the measure of its intercepted arc.

Corollary 1• If two inscribed angles intercept the
same arc, then the angles are congruent.

Corollary 2• An angle inscribed in a semicircle is a
right angle. (How very convenient…)

Corollary 3• If a quadrilateral is inscribed in a circle,
then its opposite angles are supplementary.

Theorem 9-8• The measure of an angle formed by a
chord and a tangent is equal to half the measure of the intercepted arc.
