Kite
Definition
quadrilateral in which 2 disjoint pairs of consecutive sides are congruent
Term
Square
Definition
parallelogram that is both a rectangle and a rhombus
Term
Trapezoid
Definition
a quadrilateral with exactly one pair of parallel sides. They parallel sides are called bases of the trapezoid.
Term
Isosceles trapezoid
Definition
a trapezoid in which the nonparallel sides (legs) are congruent and where the lower base angles are congruent and the upper base angles are congruent.
Term
properties of rhombus
Definition
  • properties of a parallelogram
  • properties of a kite
  • all sides are congruent
  • diagonals bisect the angles
  • diagonals are perpendicular
  • diagonals divide the rhombus into 4 congruent right triangles
Term
