Through base and height

The area of any triangle can be found, knowing the base and height. The whole simplicity of the scheme lies in the fact that the height divides the base a into two parts, and the triangle itself into two rectangular triangles, the area of which is obtained from the formula for the area of the rectangle. Then the area of the entire triangle will be the sum of the two indicated areas, and if we take one second of the height out of the bracket, we get above mentioned formula. Definition: The area of a triangle can be found as the product of half the base of the triangle (a) by its height (h):
