Area of Triangles

A triangle can be thought of as half of a parallelogram. If you cut the area of the parallelogram in half, you will get the area of one of the triangles. Therefore, we will still use the base and height to find the area of a triangle.

base height

Triangle: The area A of a triangle is one- half the base length b times the height h. AREA OF A TRIANGLE WordsNumbersFormula A = (8)(4) = 16 units bh÷ 2
