Quadrilaterals

Quadrilaterals

1. 4 sides

2. Parallelograms

   • Rhombuses
     • 4 congruent sides
     • diagonals bisect each other
     • diagonals bisect opposite angles
     • diagonals meet at a right angle
   • Rectangles
     • 4 right angles
     • all diagonals are congruent
     • Square
   • Consecutive angles are supplementary.
   • Opposite sides and angles are congruent.
   • 2 sets of parallel sides
   • Diagonals bisect each other.
   • there is a parallel side that is congruent with the opposite sides.

3. Kites

   • 2 sets of consecutive sides that are congruent and opposite sides that are not congruent
   • the diagonals meet at a right angle

4. Trapezoids

   • 1 set of parallel lines
   • the non-parallel lines are legs
   • the base angles are on each parallel line
   • isosceles Trapezoids
     • Diagonals are congruent but do not bisect
     • Consecutive base angles are congruent
