2. Happy Monday (Wednesday?)!
Do Now: Solve Algebraically:
In a pair of supplementary angles, one angle is 78° less than its supplement (i.e. the other angle). What are the measurements of the two angles.

3. Diagonals of Polygons

4. “Special” Quadrilaterals
In your groups, use the “examples” and “not examples” to create definitions of each of the quadrilaterals.
Each group will then put up their definitions and we will see what similarities we find.

5. Defintions

6. Challenge/Exit Slip/Algebra Review
A rectangle with perimeter 198 cm is divided into 5 congruent rectangles as shown below. What is the perimeter of one of the five congruent rectangles?

7. Homework:
Complete the polygons worksheet (the back side of the True/False worksheet from last week.)
