Inscribed Angles Flashcards
1
Q
What is an Inscribed Angle?
A
An angle shared by two chords with a common endpoint.
2
Q
What is the Inscribed Angle Theorem?
A
mABC=1/2mAC. The measure of an inscribed angle is half the measure of its intercepted arc.
3
Q
What is the Inscribed Angles Corollary?
A
If inscribed angles of a circle intercept the same arc or are subtended by the same chord or arc, then the angles are congruent.
4
Q
What is the Inscribed Right Angle Theorem?
A
If an inscribed angle subtends a semicircle, the angle is a right angle.
5
Q
What is the Quadrilateral Inscribed Angles Theorem?
A
If a Quadrilateral is inscribed in a Circle, then its opposite angles are supplementary.
