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.

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

USE A FORMULA TO FIND THE AREA The figure is a square A = s2

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 =

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 =

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, A =
