Define the sine function in a right triangle.

Back

Sine (SIN) is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

Define the cosine function in a right triangle.

Back

Cosine (COS) is the ratio of the length of the adjacent side to the length of the hypotenuse.

Define the tangent function in a right triangle.

Back

Tangent (TAN) is the ratio of the length of the opposite side to the length of the adjacent side.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

How do you find the angle using the sine function?

Back

Use the inverse sine function: X = sin⁻¹(opposite/hypotenuse).
