How do you find the length of a side in a right triangle?

Back

To find the length of a side in a right triangle, you can use the Pythagorean Theorem if you know the lengths of the other two sides. Alternatively, you can use trigonometric ratios (sine, cosine, tangent) if you know an angle and one side.

What is a special right triangle?

Back

A special right triangle is a right triangle with specific angle measures that allow for easy calculation of side lengths. The two most common special right triangles are the 45-45-90 triangle and the 30-60-90 triangle.

How do you find the angle of elevation?

Back

The angle of elevation is the angle formed by a horizontal line and the line of sight to an object above the horizontal line. It can be found using trigonometric ratios based on the height of the object and the distance from the observer.
