Quadrilaterals

1. 4 sides

2. Parallelograms

   • opposite sides are parallel
   • opposite sides are congruent
   • consecutive angles are supplementary
   • opposite angles are congruent
   • diagonals bisect each other
   • Rhombuses
     • diagonals meet at right angle
     • diagonals bisect angles
   • Rectangles
     • diagonals are congruent
     • Squares

3. Trapezoids

   • one set of parallel sides (bases)
   • two sets of parallel angles
   • midsegment is 1/2(BC + AD)
   • Isosceles Trapezoids
     • consecutive base angles are congruent
