SOH CAH TOA

Front

What does SOH CAH TOA stand for?

Back

SOH: Sine = Opposite/Hypotenuse, CAH: Cosine = Adjacent/Hypotenuse, TOA: Tangent = Opposite/Adjacent.

Front

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

Back

Sine of an angle = Length of the opposite side / Length of the hypotenuse.

Front

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

Back

Cosine of an angle = Length of the adjacent side / Length of the hypotenuse.

Front

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

Back

Tangent of an angle = Length of the opposite side / Length of the adjacent side.

Front

If the opposite side is 32 and the hypotenuse is 40, what is sinA?

Back

sinA = 32/40.

Front

If the adjacent side is 30 and the hypotenuse is 34, what is cosA?

Back

cosA = 30/34.

Front

If the opposite side is 32 and the adjacent side is 24, what is tanX?

Back

tanX = 32/24.

Front

What is the relationship between sine, cosine, and tangent?

Back

tanA = sinA / cosA.

Front

In a right triangle, if one angle is 30 degrees, what is the sine of that angle?

Back

sin(30°) = 1/2.

Front

In a right triangle, if one angle is 45 degrees, what is the cosine of that angle?

Back

cos(45°) = √2/2.
