1. 7.2/7.3 Parallelograms!
Learning Objective: to identify and classify parallelograms and prove that figures are special types of parallelograms.
Warm-up (IN)
List all the characteristics of parallelograms that you know.
*Opposite sides parallel
*Opposite sides congruent
*Opposite angles congruent
*Diagonals Bisect each other

2. CKC p. 349 #1 and 2 Notes Ways to prove a figure is a parallelogram -
Learning Objective: to identify and classify parallelograms and prove that figures are special types of parallelograms.
Notes
Ways to prove a figure is a parallelogram -
1 – show that both pairs of opposite sides are parallel
2 – show that both pairs of opposite angles are congruent
3 – show that one pair of opposite sides are both congruent and parallel
4 – show that diagonals bisect each other
During the CKC (checking key concepts) the students will answer the questions verbally and I will assess if they understand what makes up a parallelogram.

3. Learning Objective: to identify and classify parallelograms and prove that figures are special types of parallelograms.
Ex 1 – plot the points and show that they are the vertices of a parallelogram: (-1,5), (2,4), (-2,2), (-5,3)
The students can use distance and slope formulas to use any of the methods discussed in slide 2 to prove that the figure is a parallelogram.

4. Ways to prove a parallelogram is a rectangle -
Learning Objective: to identify and classify parallelograms and prove that figures are special types of parallelograms.
Ways to prove a parallelogram is a rectangle -
1 – show that the diagonals are congruent
2 – show that ONE angle is right
Ways to prove a parallelogram is a rhombus -
1 – show that the diagonals are perpendicular
2 – show that 2 consecutive sides are congruent
We will review the conditional statements for each of these properties.
Conditional statements!

7. Out – Use a property of parallelograms to explain why you only need one right angle to prove it’s a rectangle.
