Quadrilaterals

1. 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 angles
     • diagonals bisect angles
   • Rectangles
     • diagonals are conguruent
     • Squares

2. 4 Sides

3. Trapezoids

   • one set of parallel sides= bases
   • midsegment is half of (AB + BC)
   • 2 sets of base angles
   • Isosceles Trapezoids
     • legs are congruent
     • consecutive base angles are congruent
     • diagonal are congruent but don't bisect

4. Kites

   • 2 sets of consecutive sides are congruent
   • no opposite side is congruent
   • diagonals meet at right angles
