WebLet's suppose that you know a triangle has angles 90 and 50 and you want to know the third angle. Let's call the unknown angle x. x + 90 + 50 = 180 x + 140 = 180 x = 180 - 140 x = 40 As for the side lengths of the triangle, you need more information to figure those out. WebRight Angled Triangle. A right angled triangle is a triangle in which one of the angles is 90°. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle.Further, based on the other angle values, the right triangles are classified as isosceles right triangles and scalene right triangles.
