Inscribed Quadrilateral Theorem We Do
Inscribed Quadrilateral Theorem: If quadrilateral is inscribed in a circle, then its opposite angles are supplementary
Example 2. Find the indicated measures.
Step 1: Determine if the all the vertices of the figure lie on the circle.
(39+71
No, not inscribed
Yes, Inscribed
Step 2: Using the Inscribed Quadrilateral theorem, select a pair of opposite
angles and solve for the value X.
