Quadrilaterals

Quadrilaterals

1. Parallelograms

   • Rectangle
     • Squares
     • Diagonals are congruent
     • 4 congruent right angles
   • Rhombus
     • Parallelogram with 4 congruent sides
     • Each diagonal bisects a pair of opposite angles
     • Diagonals are perpendicular and meet at a right
     • At least one diagonal bisects a pair of opposite angles
   • 2 pairs of parallel sides
   • Opposite sides are conguent
   • Consecutive angles are supplementary
   • Opposite angles are congruent
   • Diagonals bisect each other
   • One pair of opposite sides is both congruent and parallel

2. Polygon with 4 sides

3. Trapezoid

   • Only 1 set of parallel sides
   • Legs are the lines that are not parallel and they are congruent
   • Isoceles Tapezoid
     • Base angles are congruent the opposite base angles (bottom to bottom and top to top)
     • Diagonals are congruent (but dont bisect each other)
   • Angles are supplementary to each other
   • Midsegement =1/2(BC+AD)

4. Kite

   • Diagonals are perpendicular and meet at right angles
   • 2 sets of consecutive sides are congruent, but opposite sides are not conguent
   • Diagonals bisect the angles
   • No pairs of parallel sides
