Front

What does SOHCAHTOA stand for?

Back

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

Front

What is the sine ratio in a right triangle?

Back

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

Front

What is the cosine ratio in a right triangle?

Back

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

Front

What is the tangent ratio in a right triangle?

Back

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

Front

In a right triangle, if angle P is 30 degrees, what is sin(P)?

Back

sin(30) = 1/2.

Front

In a right triangle, if angle P is 60 degrees, what is cos(P)?

Back

cos(60) = 1/2.

Front

In a right triangle, if angle P is 45 degrees, what is tan(P)?

Back

tan(45) = 1.

Front

What type of triangle is used for trigonometric ratios?

Back

Trigonometric ratios are used specifically with right triangles.

Front

If the opposite side is 3 and the hypotenuse is 5, what is sin(theta)?

Back

sin(theta) = 3/5.

Front

If the adjacent side is 4 and the hypotenuse is 5, what is cos(theta)?

Back

cos(theta) = 4/5.
