Trapezoid Midsegment

Objective: Apply trapezoid midsegment.

A trapezoid has at least one pair of parallel opposite sides in the inclusive convention used here; its midsegment averages the base lengths.

Worked examples

Objective: Apply isosceles trapezoids.

An isosceles trapezoid has congruent legs and pairs of congruent base angles.

Worked examples

Try itIsosceles trapezoid T1 has a base angle of 41°. What is the angle at the other end of that same base?Show answer

41°. Base angles of an isosceles trapezoid are congruent.

Objective: Apply kite properties.

A kite has two distinct pairs of adjacent congruent sides; one diagonal bisects the other at right angles.

Worked examples

Try itKite K1 has adjacent congruent sides of length 6. What is the length of the matching adjacent side?Show answer

6. The specified adjacent pair of sides is congruent.
