Happy word search day! (It’s on the table) WARM UP Happy word search day! (It’s on the table)

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.

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

Properties of a trapezium 0 pair of parallel sides

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

Properties of a trapezoid A trapezoid has one and only one pair of parallel sides.

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

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)

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

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)
