Theorem states that the acute angles of a right triangle are complementary. Use the corollary to set up and solve an equation. x° + 2x° = 90° Corollary to the Triangle Sum Theorem x Solve for = 30 x. So, the measures of the acute angles are 30° and 2(30°) = 60°. 4. Look Back Add the two angles and check that their sum satisfi es the Corollary

The right triangles you explored are sometimes called 45°-45°-90° and 30°-60°-90° triangles. In a 45°-45°-90° triangle, the hypotenuse is √ ― 2 times as long as each leg. In a 30°-60°-90° triangle, the hypotenuse is twice as long as the shorter leg and the longer leg is √ ―3 times as long as the shorter leg.

From right triangle XYZ, the following identities can be derived: Using Figure 2 , observe that ∠X and ∠Y are complementary. Figure 2 Reference triangles. Thus, in general: Example 3: What are the values of the six trigonometric functions for angles that measure 30°, 45°, and 60° (see Figure 3 and Table 1 ).
Nov 14, 2019 · A 45-45-90 right triangle has angles of 45, 45, and 90 degrees, and is also called an Isosceles Right Triangle. It occurs frequently on standardized tests, and is a very easy triangle to solve. The ratio between the sides of this triangle is 1:1:Sqrt(2) , which means that the length of the legs are equal, and the length of the hypotenuse is ...
