Quadrilaterals

Quadrilaterals

1. Parallelograms

   • 2 sets of parallel sides
   • Rhombus
     • 4 congruent sides
     • Diagonals meet at a right angle
     • Diagonals bisect the angles
   • Rectangle
     • 4 right angles
     • Diagonals are congruent
     • Square
   • There is a parallel side that is congruent with the opposite side
   • Diagonals bisect each other
   • Opposite sides and angles are congruent
   • Consecutive angles are supplementary

2. 4 sides

3. Trapezoids

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

4. Kites

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