SOHCAHTOA Review

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic for remembering the definitions of the sine, cosine, and tangent functions: - SOH: Sine = Opposite / Hypotenuse - CAH: Cosine = Adjacent / Hypotenuse - TOA: Tangent = Opposite / Adjacent

Front

Define sine in terms of a right triangle.

Back

Sine (sin) of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

Define cosine in terms of a right triangle.

Back

Cosine (cos) of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

Define tangent in terms of a right triangle.

Back

Tangent (tan) of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

Front

If sinA = 0.5, what is the measure of angle A?

Back

Angle A is 30 degrees.

Front

If cosB = 0.6, what is the measure of angle B?

Back

Angle B is approximately 53.13 degrees.

Front

What is the tangent of a 45-degree angle?

Back

The tangent of a 45-degree angle is 1.

Front

How do you find the length of a side using the sine function?

Back

To find the length of a side using sine, use the formula: Opposite = Hypotenuse * sin(angle).

Front

How do you find the length of a side using the cosine function?

Back

To find the length of a side using cosine, use the formula: Adjacent = Hypotenuse * cos(angle).
