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.

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.

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

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

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

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

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

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

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

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