1. GEOMETRY EOC

2. Parallelogram  Opposite angles are equal.  Consecutive angles are supplementary.  Opposite sides are congruent.  Any side can be considered a base.  The altitude is the perpendicular distance from the base to the opposite side.  The diagonals bisect.

17. Properties of an Isosceles Trapezoid  The bases (top & bottom) of an isosceles trapezoid are parallel.  Opposite sides of an isosceles trapezoid are the same length (congruent)  The angles on either side of the bases are the same size/measure(congruent)  The diagonals are congruent  Adjacent angles (next to each other) along the sides are supplementary. That means their measures adds up to 180 degrees.
