A cyclic quadrilateral is a quadrilateral that is convex and whose vertices lie on a circle. A quadrilateral n ABCD is inscribed in the circle if all the vertices ofn ABCD lie on.

Proving That a Quadrilateral is a Square The following method can be used to prove that a quadrilateral is a square: If a quadrilateral is both a rectangle and a rhombus, then it is a square.
•A diagonal of a quadrilateral is a line segment whose endpoints are two nonadjacent vertices of the quadrilateral, such as and . •The sum of the measures of the angles of a quadrilateral is 360 degrees.
Euclidean and Non-Euclidean Geometry - Fall 2007 Dr. Hamblin Presentation: Cyclic Quadrilaterals In this presentation, you will investigate a special class of quadrilaterals known as "cyclic quadrilaterals.By definition, a cyclic quadrilateral is one where all four vertices lie on a single circle.
particular quadrilateral (as explored fairly extensively in De Villiers, 1996) can easily be found simply by reflection in the line of symmetry.
Usually the next section in geometry texts is proving a quadrilateral is a parallelogram and this lesson could serve as the next day's lesson after that introductory day.
3 Overview Day 1: The lesson begins with a discussion in regards to the definition of a quadrilateral and the terms referring to the parts of the quadrilateral.
