• 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.
