WebFeb 10, 2024 · Assign variables a, b, and c to the sides of your triangle. The variable "c" will always be assigned to the hypotenuse, or longest side. Choose one of the other sides to be a, and call the other side b (it doesn't matter which is which; the math will turn out the same). Then copy the lengths of a and b into the formula, according to the following example:
WebApr 25, 2016 · To find the area of a triangle, you need to know the length of one side — the base ( b for short) — and the height (h). Note that the height forms a right angle with the base.
