Trapezoid

**//Trapezoid//** is a quadrilateral with one pair of parallel opposite sides
 * __Definition__ **

//Angle Properties// ** ** 1. ** *Consecutive angles are supplementary Example Proof: Prove: Angle RAP and Angle TRA are supplementary This is the most important property of a trapezoid for the following reasons: - Given only one angle measurement from the two consecutive angle pair, the other angle measurement can be known using this property
 * __Properties__ **
 * This property applies only to the indicated pairs of consecutive angles below (Angle RTP & Angle TPA, Angle TRA & Angle RAP)
