Kite A quadrilateral with 2 pairs of consecutive congruent sides, but opposites sides are NOT parallel

Some Special Properties of Kite Diagonals are perpendicular

A quadrilateral with 1 pair of parallel sides called bases Trapezoid A quadrilateral with 1 pair of parallel sides called bases

Have only one pair of opposite sides that are parallel. Trapezoids Have only one pair of opposite sides that are parallel. base leg

Isosceles Trapezoid A quadrilateral with 1 pair of parallel sides called bases and non-parallel sides are congruent (legs)

Some Special Properties of Isosceles Trapezoid Diagonals are congruent

Classifying Triangles by Sides Equilateral – 3 congruent sides Isosceles – 2 congruent sides Scalene – No sides congruent
