In any worksheets on area of a Triangle, you will have to find the area of many types of triangles such as right angled triangles, isosceles, scalene or equilateral triangles. To find the area of a Triangle in any area of Triangle worksheets, all you really need to know is a simple formula for finding the area of a Triangle. With this area of a Triangle formula, you will be able to solve any problems on any area of a Triangle worksheets.

Let’s examine the formula for the area of a Triangle and how it might be useful on any worksheets on area of a Triangle.

Formula for area of a Triangle

For any Triangle, there must be a height of the triangle. Whether the triangle is scalene, isosceles or right angled, the height of the triangle is the perpendicular distance from the base of the triangle to an angle of the triangle. The height of a triangle is shown below.

In both triangles, h is the perpendicular height and b is the base of the triangle which is ALWAYS perpendicular to the height of the triangle. The area of the triangle is given by:

In worksheets on area of a triangle, you may not be asked to find the area of a triangle but to find either the base or the height of a triangle. In this case, you will need to rearrange the formula for area of a triangle above to find the base or the height. If you are required to find the other sides of the triangle in your worksheets of area of a triangle, then you will have to use the Pythagorean Theorem to find the other sides of the triangle. See Pythagorean Math Worksheets for practice.
