What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

How can you use trigonometric ratios to find a missing side in a right triangle?

Back

You can use the appropriate trigonometric ratio (sine, cosine, or tangent) based on the known angle and the sides you have to set up an equation and solve for the missing side.
