  1. Quadrilaterals (4 sided shapes) 9.3.3.7 Use properties of polygons—including quadrilaterals and regular polygons—to define them, classify them, solve problems and logically justify results.

  2. Lesson Obj: IWBAT identify different quadrilaterals and solve using their properties. How many degrees are there in a quadrilateral? • Major Quadrilaterals • Parallelogram • Square • Rhombus • Rectangle • Kite • Trapezoid • Isosceles Trapezoid Guiding Question: What defines different quadrilaterals?

  3. Parallelogram • Opp. Sides are parallel • Opp. Sides are congruent • Diagonals bisect • Opp. Angles are congruent • Consecutive angles are supplementary. Guiding Question: What defines different quadrilaterals?

  4. Rectangle • Parallelogram (all those rules are true) • 4 right angles • DIAGONALS ARE CONGRUENT Guiding Question: What defines different quadrilaterals?

  5. Square • Parallelogram • Rectangle • All sides are congruent • Diagonals bisect opposite angles Guiding Question: What defines different quadrilaterals?

  6. Rhombus • Parallelogram • All congruent sides • Diagonals are perpendicular • Diagonals bisect the opposite angles Guiding Question: What defines different quadrilaterals?

  7. Assignment: Quad Properties and Classifying Quadrilaterals Guiding Question: What defines different quadrilaterals?
