Front

What is the sine ratio in trigonometry?

Back

Sin (O/H) - Sine is the ratio of the length of the opposite side to the length of the hypotenuse in a right triangle.

Front

What is the cosine ratio in trigonometry?

Back

Cos (A/H) - Cosine is the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.

Front

What is the tangent ratio in trigonometry?

Back

Tan (O/A) - Tangent is the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

Front

What does CAH stand for in trigonometry?

Back

CAH stands for Cosine = Adjacent/Hypotenuse.

Front

What does TOA stand for in trigonometry?

Back

TOA stands for Tangent = Opposite/Adjacent.

Front

What is the relationship between sine and cosine?

Back

Sine and cosine are complementary functions; sin(θ) = cos(90° - θ).

Front

How do you find the hypotenuse using sine?

Back

Hypotenuse = Opposite/Sin(θ).

Front

How do you find the adjacent side using cosine?

Back

Adjacent = Hypotenuse * Cos(θ).

Front

How do you find the opposite side using tangent?

Back

Opposite = Adjacent * Tan(θ).

Front

What is the Pythagorean theorem?

Back

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