1. Areas of Triangles and Special Quadrilaterals
Chapter 6 Section 6.7A
Areas of Triangles and Special Quadrilaterals
Find formulas for the area of triangles, and special quadrilaterals. Use these formulas to find the area of triangles, and special quadrilaterals.

2. Something Different
You are to work by yourself, or with your neighbor to answer the following questions. You must answer all the questions with complete sentences. You will need to refer to the resource pages provided to answer some questions.
You have 20 minutes to answer all questions and turn in any work Mr. Sutton asks for.

3. AREA FORMULA FOR A SQUARE
Postulate
A = s2
Side (s)

4. The figure is a square A = s2 A = 82 A = 64 square units
USE A FORMULA TO FIND THE AREA
The figure is a square
A = s2
A = 82
A = 64 square units

5. Area = (Base)(Height): A = bh
AREA FORMULA OF A RECTANGLE
Theorem
Base (b)
Height (h)
Area = (Base)(Height):
A = bh

6. Since the figure is a rectangle, A = bh
USE A FORMULA TO FIND THE AREA
Since the figure is a rectangle, A = bh
A = 9(3)
A = 27 square units

7. Area = (Base)(Height): A = bh
AREA FORMULA OF A PARALLELOGRAM
Theorem b c h
Area = (Base)(Height):
A = bh

8. Since the figure is a parallelogram, A = bh
USE A FORMULA TO FIND THE AREA
Since the figure is a parallelogram, A = bh
A = 11(9)
A = 99 square units

9. AREA FORMULA OF A TRIANGLE
Theorem
Base (b)
Height (h)

10. Since the figure is a triangle,
USE A FORMULA TO FIND THE AREA
Since the figure is a triangle,
Square units
