SOH CAH TOA

Front

What does SOH CAH TOA stand for?

Back

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

Front

What is the sine function?

Back

The sine function (sin) 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 function?

Back

The cosine function (cos) 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 function?

Back

The tangent function (tan) is the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.

Front

If you know the opposite side and the hypotenuse, which function do you use?

Back

You use the sine function.

Front

If you know the adjacent side and the hypotenuse, which function do you use?

Back

You use the cosine function.

Front

If you know the opposite side and the adjacent side, which function do you use?

Back

You use the tangent function.

Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the longest side of a right triangle, opposite the right angle.

Front

Which side is the adjacent side relative to angle G in triangle EMG?

Back

The adjacent side is MG.

Front

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

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (Pythagorean theorem).
