WebDec 19, 2015 · 1. In fact, once you have spotted that it is a right triangle there is a simple formula for the diameter of the inscribed circle. d = a + b − c. So your radius is: r = ( 8 + 15 − 17) / 2 = 3. It follows from two ways to compute the area of the triangle: A = a b / 2. WebExamples: find the perimeter of a triangle. Example 1: In the simplest scenario one has measured all three sides of a triangle and then it is a matter of simple summation to find the perimeter. For example, if the sides are 3 in, 4 in, and 5 in, then the perimeter is simply 3 + 4 + 5 = 12 inches in total.
