Trig Ratios

Front

What are the three primary trigonometric ratios?

Back

Sine, Cosine, Tangent.

Front

Define Sine in terms of a right triangle.

Back

Sine = Opposite side / Hypotenuse.

Front

Define Cosine in terms of a right triangle.

Back

Cosine = Adjacent side / Hypotenuse.

Front

Define Tangent in terms of a right triangle.

Back

Tangent = Opposite side / Adjacent side.

Front

What mnemonic helps remember the trigonometric ratios?

Back

Soh Cah Toa.

Front

If the hypotenuse is 10 and the opposite side is 6, what is the sine?

Back

Sine = 6/10 = 0.6.

Front

If the adjacent side is 8 and the hypotenuse is 10, what is the cosine?

Back

Cosine = 8/10 = 0.8.

Front

If the opposite side is 5 and the adjacent side is 12, what is the tangent?

Back

Tangent = 5/12.

Front

What is the Pythagorean theorem?

Back

a² + b² = c², where c is the hypotenuse.

Front

How do you find the angle using sine?

Back

Angle = sin⁻¹(Opposite / Hypotenuse).
