This document provides instructions for calculating the area of a triangle. It explains that to find the area, you measure the height as the perpendicular distance from the opposite vertex to the base. The area of the triangle is then calculated as one-half the area of the rectangle formed by the height and base, using the formula: Area of triangle = 1/2 x height x base. Some examples of using this formula to calculate triangle areas are also provided.

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

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

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

8. examples:

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