Midterm Flashcards
Kite
A quadrilateral with two distinct pair of congruent consecutive sides.
Kite Sides
two pairs of adjacent congruent sides
Kite Angles
- non vertex angles are congruent
- Vertex angles are bisected by diagonal
Kite Diagonals
- perpendicular diagonals
- Diagonal of vertex angles bisects diagonal of non-vertex angles
Trapezoid
A quadrilateral with exactly one pair of parallel sides
Trapezoid Sides
The two parallel sides are called bases
Isosceles trapezoid sides
non-parallel sides are congruent
Trapezoid Angles
Consecutive angles between the bases are supplementary
Isosceles Trapezoid
trapezoid with two congruent legs
Isosceles trapezoid angles
