  37. Properties of a Parallelogram

  38. Parallelogram • Opposite sides are congruent. • Opposite sides are parallel. • Opposite angles are congruent. • Diagonals bisect each other. • Consecutive (adjacent) angles are supplementary (+ 180 degrees). • Sum of the interior angles is 360 degrees.

  39. Properties of a Rectangle

  40. Rectangle • All properties of a parallelogram. • All angles are 90 degrees. • Diagonals are congruent.

  41. Properties of a Rhombus

  42. Rhombus • All properties of a parallelogram. • Diagonals are perpendicular (form right angles). • Diagonals bisect the angles.

  43. Properties of a Square

  44. Square • All properties of a parallelogram. • All properties of a rectangle. • All properties of a rhombus.

  45. Properties of an Isosceles Trapezoid

  46. Isosceles Trapezoid • Diagonals are congruent. • Opposite angles are supplementary + 180 degrees. • Legs are congruent
