Exploring Inscribed Quadrilaterals in Circles

This video tutorial covers the concept of inscribed quadrilaterals in circles, focusing on their properties, such as opposite angles being supplementary. Through examples, it demonstrates how to find missing variables in these quadrilaterals by applying the supplementary angle property and calculating angles using intercepted arcs.

What is the sum of the opposite angles in an inscribed quadrilateral?

• 180 degrees

• 270 degrees

• 90 degrees

• 360 degrees
