Last time we talked about the properties of quadrilaterals
Last time we talked about the properties of quadrilaterals. Please get your notes out and make sure we got them all.
3
Any four sided polygon is a quadrilateral.
All convex quadrilaterals have: 4 sides 4 angles Interior angles add to 360° Special quadrilaterals in this section: Parallelogram Rhombus Rectangle Square Trapezoid Trapezium Kite
4
Properties of a trapezium
0 pair of parallel sides
5
Properties of a kite (a kite is a special trapezium)
2 pair of congruent sides Consecutive sides are congruent Opposite sides are NOT congruent Diagonals are perpendicular Notice only ONE diagonal is bisected
6
Properties of a trapezoid
A trapezoid has one and only one pair of parallel sides.
7
Properties of parallelograms
Opposite sides of a parallelogram are parallel Opposite sides are congruent Opposite angles of a parallelograms are congruent. Diagonals of a parallelogram bisect each other Consecutive angles of a parallelogram are supplementary supplementary
8
Properties of Rhombuses (Rhombi)
A rhombus is a parallelogram (this means it has ALL of the characteristics of a parallelogram) In addition: A rhombus has four congruent sides The diagonals of a rhombus are perpendicular The diagonals bisect opposite angles (you know I can’t draw this on powerpoint)
9
Properties of Rectangles
A rectangle is a parallelogram (this means it has ALL the characteristics of a parallelogram) IN ADDITION: Four right angles The diagonals of a rectangle are congruent and they bisect each other
10
Properties of Squares (the love child)
A square is a rectangle (dad), and a rhombus (mom) It has ALL those characteristics!!! four congruent sides (mom) four right angles (dad) The diagonals of a square: bisect each other (dad) are congruent (dad) are perpendicular (mom) Bisect opposite angles (mom)
