Rules for Special Right Triangles: There are two special types of right triangles that we will be studying, the 45-45-90, and the 30-60-90. 45 – 45 – 90 30 – 60 – 90. This type of triangle is also isosceles. Rules for the 45-45-90 Right Triangle: If given one of the legs, multiply one leg by √2 to find the hypotenuse.
