  • Trapezoid:
  • A with exactly pair of sides.
  • Properties:
  • : the parallel sides
  • : the non-parallel sides
  • : angles formed by a and a
  • In trap ABCD, A & B and C & D are , so they are
  • Isosceles Trapezoid: A trapezoid with legs.
  • Theorem: The base angles of an isosceles trapezoid are
  • If trap WXYZ has WZ  XY, then W X and Y Z .
  • Median of a Trapezoid:
  • A segment in a trapezoid that connects the of the non-parallel sides.
  • Example:

LO is the median

of the trapezoid.

O is the of JN.

L is the of KM.
