Presentation transcript:

Use properties of polygons—including quadrilaterals and regular polygons—to define them, classify them, solve problems and logically justify results.

* Lesson Obj: IWBAT use the properties of trapezoids and kites to solve and justify results.

* Kite 1. NOT a parallelogram 2. Diagonals are perpendicular 3. Short diagonal gets bisected 4. Top and bottom angles are bisected

* Trapezoid 1. NOT a parallelogram 2. 1 pair of parallel sides 3. Diagonals are not congruent (Unless its isosceles)

* In a trapezoid, the mid-segment (red) is the average of the 2 bases.

* Isosceles Trapezoid 1. NOT a parallelogram 2. 2 non-parallel sides are congruent 3. Base angles are congruent. 4. Diagonals are congruent

* Assignment: Properties of Quadrilaterals WS
