Match the following

• The endpoints of a diameter lie on an inscribed angle if & only if they inscribed angle is 90⁰

• Inscribed Quadrilateral Theorem

• Angles that are opposite each other and formed by two intersecting straight lines, are congruent.

• Vertical Angles Theorem

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

• Arc Additional Postulate

• If a quadrilateral is inscribed in a circle, then its opposite angles add up to 180⁰

• Inscribed Angle Theorem

• The measure of an arc formed by two adjacent arcs is the sum of the measure of the two arcs.

• Inscribed Angle of a Diameter Theorem
