Sides of a kite shape, that are next to each other (adjacent sides) are the same length on a kite.
Angles that are opposite each other and between the two different length sides are congruent (equal).
Diagonals of a kite are perpendicular to one another

Property of Quadrilateral
What is a quadrilateral? The key to a quadrilateral is found in it's name, " Quad" meaning four and " lateral" meaning side. So a quadrilateral is a four sided polygon. In addition a quadrilateral can be convex or concave. A concave quadrilateral has has one reflex angle, or an angle greater than 180 degrees. The reflex angle creates a cavity or a cave, which becomes an easy method to remember a concave quadrilateral. An example of a concave quadrilateral is a dart. A “complex quadrilateral” or “self-intersecting” quadrilateral have non-adjacent sides that cross over.
