7.4 Trapezoids, rhombi, and kites
Properties of Trapezoids, Rhombi, and Kites
Master the side, angle, and diagonal properties of trapezoids, rhombi, and kites with clear rules and step-by-step examples.
What You'll Learn
Identify a trapezoid by exactly one pair of parallel sides called bases.
Apply the midsegment formula to find the length of a trapezoid's midsegment from its two bases.
Recognize that a rhombus has four equal sides with diagonals that bisect each other at right angles.
Use the rule that consecutive angles between a rhombus's parallel sides are supplementary.
Distinguish a kite from a rhombus by comparing two pairs of adjacent equal sides versus four equal sides.
Calculate unknown angles in a kite using the property that one pair of opposite angles is congruent.
