6-5 Trapezoids and KitesM11.C.1 2.9.11.CObjectives:1) To verify and use properties of trapezoids
and kites.
Trapezoid PropertiesThe parallel sides are its bases,
and the nonparallel sides its legs. Two angles that share a base of a trapezoid are base angles.
TheoremThe base angles of an isosceles
trapezoid are congruent.
ExampleXYZW is an isosceles trapezoidm∠X = 156°m∠Ym∠Zm∠W
TheoremsThe diagonals of
an isosceles trapezoid are congruent.
The diagonals of a kite are perpendicular.
ExampleIsosceles trapezoid ABCD has diagonal AC and BD. AC = x + 5 and BD = 2x – 13. Find x.
ExampleFind m∠1, m∠2 and m∠3
