WebSo if we have a triangle with sides 3, 4, and 5 inches, the area would be 6 square inches (since it's a right triangle). So, you multiply it out: abc is 3" times 4" times 5" or 60 cubic inches. Divide 60 cubic inches by 4 to get 15 cubic inches. Divide 15 cubic inches by 6 square inches (the area) to get 2.5 inches! WebIn geometry, the incircle or inscribed circle of a triangle is the largest circle contained in the triangle; it touches (is tangent to) the three sides. The center of the incircle is called the triangle's incenter.
