E N D
Parallelograms A four sided figure with both pairs of opposite sides parallel
Some Special Properties of Parallelograms • Opposite sides are congruent • Diagonals bisect each other • Both pairs of opposite sides are parallel
Rectangle A parallelogram with 4 right angles
Some Special Properties of Rectangles • All the properties of a parallelogram • Diagonals are congruent • 4 right angles
Rhombus A parallelogram with 4 congruent sides
Some Special Properties of Rhombus • All the properties of a parallelogram • Diagonals are perpendicular • 4 congruent sides
Square A parallelogram with 4 congruent sides & 4 right angles
Some Special Properties of Square • All the properties of a parallelogram, rectangle, & rhombus
Kite A quadrilateral with 2 pairs of consecutive congruent sides, but opposites sides are NOT parallel
Some Special Properties of Kite • Diagonals are perpendicular
Trapezoid A quadrilateral with 1 pair of parallel sides called bases
base leg leg base Trapezoids Have only one pair of opposite sides that are parallel.
Isosceles Trapezoid A quadrilateral with 1 pair of parallel sides called bases and non-parallel sides are congruent (legs)
Some Special Properties of Isosceles Trapezoid • Diagonals are congruent
Classifying Trianglesby Sides • Equilateral – 3 congruent sides • Isosceles – 2 congruent sides • Scalene – No sides congruent
