8.5 Kites & Trapezoids Proving Kite Properties
Kite Non-vertex Angles Thm The non-vertex angles of a kite are
congruent. Kite Angle Bisector Thm The vertex angles of a kite are
bisected by a diagonal. Kite Diagonals Thm The diagonals of a kite
are perpendicular. Kite Diagonal Bisector Thm The diagonal
connecting the vertex angles of a kite is the perpendicular
bisector of the other diagonal. Proving Trapezoid Properties
Trapezoid Consecutive Angles Thm The consecutive angles between the
bases of a trapezoid are supplementary. Isosceles Trapezoid Thm The
base angles of an isosceles trapezoid are congruent. Converse
Isosceles Trapezoid Diagonals Thm A trapezoid is isosceles if and
only if its diagonals are congruent. Examples (Discovering Geometry
