WebSep 15, 2024 · Since the two legs of the triangle ABC have the same length, ABC is an isosceles triangle, which means that the angles A and B are equal. So since A + B = 90 ∘, this means that we must have A = B = 45 ∘. By the Pythagorean Theorem, the length c of the hypotenuse is given by c2 = 12 + 12 = 2 ⇒ c = √2 Thus, using the angle A we get: WebIf you know two angles of a triangle, it is easy to find the third one. Since the three interior angles of a triangle add up to 180 degrees you can always calculate the third angle like this: Let's suppose that you know a triangle has angles 90 and 50 and you want to know the …
