2. Things to remember about QUADRILATERALS 1. Sum of the interior angles = 360 2. All Parallelograms have:  opposite sides parallel and congruent  opposite angles congruent  NON Congruent, but bisected diagonals. 3. Rhombuses have:  Four congruent sides  Diagonals are PERPENDICULAR but NOT CONGRUENT 4. Isosceles Trapezoids have:  ONE pair of congruent legs  Two pairs of congruent base angles  Congruent BUT NOT bisected Diagonals.
