1 Lesson Plan #47 Class: Geometry Date: Tuesday January 18th, 2016 Topic: Parallelograms Aim: What are some properties of parallelograms? Objectives: 1) Students will know the properties of a parallelogram. 2) Students will be able to use the properties of a parallelogram HW #47: Do Now: Assignment #1: Given the quadrilateral below, name 1) A pair of consecutive vertices. 2) A pair of consecutive or adjacent sides. 3) Name a pair of opposite sides. 4) Name a pair of consecutive angles. 5) Name a pair of opposite angles 6) Name 2 diagonals. Assignment #2: How would you define a parallelogram? Assignment #3: Μ Μ Μ Μ Given: Parallelogram ABCD with diagonal π΄πΆ Prove: βπ΄π΅πΆ ≅ βπΆπ·π΄ Theorem: PROCEDURE: Write the Aim and Do Now Get students working! Take attendance, give back HW and collect HW Go over the Do Now Statements Reasons 2 Properties of Parallelograms: 1) Opposite sides are parallel 2) A diagonal divides it into two congruent triangles 3) Opposite sides are congruent 4) Opposite angles are congruent 5) Consecutive angles are supplementary 6) The diagonals bisect each other Online Activity: http://www.mathsisfun.com/definitions/parallelogram.html http://www.mathsisfun.com/geometry/parallelogram.html http://www.mathwarehouse.com/geometry/quadrilaterals/parallelograms/ Assignment #4: Complete the exercises below: Why?
