SOHCAHTOA Practice

Front

What does SOHCAHTOA stand for?

Back

SOHCAHTOA is a mnemonic for remembering the definitions of sine, cosine, and tangent in a right triangle: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

Front

What is the formula for Sine?

Back

Sine = Opposite/Hypotenuse.

Front

What is the formula for Cosine?

Back

Cosine = Adjacent/Hypotenuse.

Front

What is the formula for Tangent?

Back

Tangent = Opposite/Adjacent.

Front

If the opposite side is 21 and the hypotenuse is 28, what is the sine of the angle?

Back

Sine = 21/28.

Front

If the adjacent side is 35 and the hypotenuse is 28, what is the cosine of the angle?

Back

Cosine = 35/28.

Front

If the opposite side is 8 and the adjacent side is 12, what is the tangent of the angle?

Back

Tangent = 8/12.

Front

How do you find the tangent of an angle in a right triangle?

Back

Tangent is found by dividing the length of the opposite side by the length of the adjacent side.

Front

What is the relationship between the angles in a right triangle?

Back

The sum of the angles in a right triangle is always 180 degrees, with one angle being 90 degrees.

Front

If one angle in a right triangle is 41 degrees, what is the measure of the other non-right angle?

Back

The other angle = 180 - 90 - 41 = 49 degrees.
