WebIsosceles right triangle is a special right triangle, sometimes called a 45-45-90 triangle. In such triangle the legs are equal in length (as a hypotenuse always must be the longest of the right triangle sides): One leg is a base and the other is the height – there is a right angle between them. So the area of an isosceles right triangle is: WebTo find the area of a right triangle we only need to know the length of the two legs. We don’t need the hypotenuse at all. That’s because the legs determine the base and the height of the triangle in every right triangle. So we use the general triangle area formula (A = base • height/2) and substitute a and b for base and height.

Assume the triangle has sides a, b and c and angles A, B and C (where angle A is opposite side a etc.). Calculate angle A from the law of cosines. Then: a^2 = b^2 +c^2 - 2*b*c*cos(A) so: A = arccos((b^2 + c^2 - a^2)/(2*b*c)) -----(1) Then, … WebMath Warehouse's popular online triangle calculator: Enter any valid combination of sides/angles(3 sides, 2 sides and an angle or 2 angle and a 1 side) , and our calculator will do the rest!
