1 pair opposite angles equal (angles between unequal sides) The diagonal between equal sides bisects the other diagonal. The diagonal between equal sides bisects the interior angles. The diagonals intersect at 90°.
Using Properties of Trapezoids. A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are the bases. Base angles of a trapezoid are two consecutive angles whose common side is a base. A trapezoid has two pairs of base angles.
Here are some examples of squares: All squares possess the following properties: • Opposite sides of a square are parallel • All sides of a square are equal • All angles at the vertices of a square are 90 • The diagonals of a square are equal • The diagonals of a square bisect the opposite angles
A trapezoid is a quadrilateral with exactly one pair of parallel sides. The parallel sides are the bases. A trapezoid has two pairs of base angles. For instance, in trapezoid ABCD, TMD and TMC are one pair of base angles. The other pair is TMA and TMB.
‐ use slope formula to show that we have 2 pairs of equal slopes that are negative reciprocals ‐ use distance formula to find all 4 lengths...they must all be equal

Definition of Trapezoid. A trapezoid is a four-sided closed 2D figure which has an area and its perimeter. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.
