1. basic concepts area and perimeter

2. The perimeter of a triangle is the measure around the triangle = a + b + c

3. To find the area of a triangle: The height = the perpendicular distance from the opposite vertex to the base

4. To find the area of a triangle: The height = the perpendicular distance from the opposite vertex to the base

5. The area of this rectangle is height x base To find the area of a triangle: The height = the perpendicular distance from the opposite vertex to the base

6. The area of this rectangle is height x base The area of the triangle is ½ the area of the rectangle To find the area of a triangle: The height = the perpendicular distance from the opposite vertex to the base

7. The area of this rectangle is height x base The area of the triangle is ½ the area of the rectangle h Area of triangle = ½ h b b To find the area of a triangle: The height = the perpendicular distance from the opposite vertex to the base

8. examples:

9. area = ½ ( 4 )( 7 ) = 14 square units area = ½ ( 3 )( 6 ) = 9 square units area = ½ ( h )( b ) area = ½ ( 5 )( 9 ) = 22 ½ square units
