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

Back

To find a missing side in a right triangle, you can use the Pythagorean theorem or trigonometric ratios (sine, cosine, or tangent) depending on the information given.

When should you use the sine function?

Back

Use the sine function when you know the length of the opposite side and the hypotenuse, or when you need to find the angle opposite a known side.

Front

When should you use the cosine function?

Back

Use the cosine function when you know the length of the adjacent side and the hypotenuse, or when you need to find the angle adjacent to a known side.

Front

When should you use the tangent function?

Back

Use the tangent function when you know the lengths of the opposite and adjacent sides, or when you need to find the angle based on these sides.

What is the first step in solving a right triangle problem?

Back

The first step is to identify which sides and angles are known and which need to be found. Then, choose the appropriate method (Pythagorean theorem or trigonometric ratios) to solve.
