1. 4 sides

2. parallelograms

   • Opposite sides are congruent
   • Consecutive angles are supplementary
   • Opposite angles are congruent
   • Diagonal lines bisect each other
   • Rhombus
     • Qudrilateral with 4 congruent sides
     • Diagonal lines meet at a right angle
     • Diagonal lines bisect the angles
     • Square
       • palleogram with 4 right angles and 4 congruent sides
       • Diagonals are congruent
   • Rectangle
     • Diagonal lines are congruent
     • All angles are right angles

3. Trapezoid

   • 1 set of parallel sides
   • Legs are not parallel
   • The bases are parallel
   • Midsegments are half the length of the bases
   • Isosceles trapezoid
     • Legs are congruent
       • Angles that are on the same bases are congruent
         • Diagonal lines are congruent, but do not bisect each other
