What are the special right triangles?

Although all right triangles have special features – trigonometric functions and the Pythagorean theorem. The most frequently studied right triangles, the special right triangles, are the 30, 60, 90 Triangles followed by the 45, 45, 90 triangles. The picture below illustrates the general formula for the 30, 60, 90 Triangle.

What are some special angle values?

Special Angle Values: 30-60-90 and 45-45-90 Triangles | Purplemath Explains a simple pictorial way to remember basic reference angle values. Provides other memory aids for the values of trigonometric ratios for these “special” angle values, based on 30-60-90 triangles and 45-45-90 triangles.

What is the proportion of a special triangle?

Special triangles are right triangles that have special proportions for their sides. The 30°-60°-90° triangle has the proportions 1:√3:2. The 45°-45°-90° triangle has the proportions 1:1:√2.

What is a 30° 60° 90° triangle?

A 30°-60°-90° triangle is a right triangle that contains the acute angles 30° and 60°. The sides of these triangles have lengths with special proportions. We can obtain these proportions using the Pythagorean theorem.
