Trapezoids

exactly on pair parrallel sides

Trapezoid Consecutive Angles Conjecture

the consecutive angles between the bases of a trapezoid are parrallel and have 180 degree supplementary angles

What Are the Properties Of Kites?

 

 

 

Kite

two pairs of consecutive congruent sides

ex:

http://www.wyzant.com/Help/Math/Geometry/Areas/Rhombuses_and_Kites.aspx

In kite abcd, segment ab is congruent to bc because the angles are adjacent to each other. It's the same with segments ac and dc.

 

 

Properties of Kites

1) the nonvertex angles are congruent

2) diagonals are perpendicualar

3) the vertex diagnal bisects the other diagonal

4) the vertex diagonsl is an angle bisector of the vertex.
