The Pythagorean Theorem is great for finding the third side of a right triangle when you already know two other sides. There are some triangles like 30-60-90 and 45-45-90 triangles that are so common that it is useful to know the side ratios without doing the Pythagorean Theorem each time.Learn to find the sine, cosine, and tangent of 45-45-90 triangles and also 30-60-90 triangles. Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without using a calculator.E. x 2 2. Solution. Answer: C. Justification: Cutting the 1 by 1 square along its diagonals gives a 45-45-90 triangle with hypotenuse 1, so the ratio of the lengths of the sides is x : x :1. The ratio 1:1: 2 must be scaled so that the hypotenuse is 1. Dividing by 2 gives. x : x : 1 1 :1: 2. (Divide by 2 )The 45-45-90 triangle has three unique properties that make it very special and unlike all the other triangles. Hence, a 45°−45°−90° triangle is a commonly encountered right triangle whose sides are in the proportion 1:1:√2. To know more about the 45°-45°-90 rule:A 30-60-90 degree triangle is a special right triangle, so it's side lengths are always consistent with each other. The ratio of the sides follow the 30-60-90 triangle ratio: 1:2:\sqrt {3} 1: 2: 3. Short side (opposite the 30 degree angle) = x. Hypotenuse (opposite the 90 degree angle) = 2x. Long side (opposite the 60 degree angle) = x√3.In a 30-60-90 triangle, the angles are 30 degrees, 60 degrees, and 90 degrees.
