5.11. Properties of Trapezoids and Kites. The slopes of DE and CF are the same, so DE ___ CF. The slopes of EF and CD are not the same, so EF is ______________ to CD. Use a coordinate plane. Example 1. Show that CDEF is a trapezoid. Solution. Compare the slopes of the opposite sides.

EXAMPLE 2

Arch. The stone above the arch in the diagram is an isosceles trapezoid. Find m K , m M , and m J. STEP 1. Find m K . JKLM is an isosceles trapezoid, so K and L are congruent base angles, and m K = m L = 85 o. EXAMPLE 2. Use properties of isosceles trapezoids. SOLUTION.
