What is a cyclic quadrilateral?
-
@TSS-Graviser A cyclic quadrilateral is a 4-sided figure that can be drawn inside a circle with its corners touching the circle, like this:
You'll see in the lesson that opposite angles of the cyclic quadrilateral add up to \( 180^{\circ}\). There is also something else called Ptolemy's Theorem, which we don't learn in Module 2, but later on in Module 8 (which isn't available yet). This says that the sum of the products of pairs of sides equals the product of the diagonals. Cyclic quadrilaterals are coooool!
