What are some properties of trapezoids ?

Steps 1, 2 and 3

Draw parallel segments of unequal length. Draw two nonparallel sides connecting them to make a trapezoid Measure the angles copy and complete

Trapezoid Consecutive Angles Conjecture

The consecutive angles between the bases of a trapezoids are supplementary

Isosceles Trapezoid Conjecture

The base angles of an isosceles trapezoid are congruent

Isosceles Trapezoid Diagonals Conjecture

The diagonals of an isosceles trapezoid are congruent
