A 45-45-90 triangle is a right triangle with angles that are 45 degrees, 45 degrees, and 90 degrees. The ratio of the sides in a 45-45-90 triangle is always 1:1:sqrt (2). This means that if the length of one side of the triangle is "x," then the length of the other two sides will also be "x." What is 30-60-90 triangle?
