Soh Cah Toa Flashcard #1

Front

What is the definition of 'adjacent side' in a right triangle?

Back

The side that is next to the angle of interest, not the hypotenuse.

Front

What is the definition of 'opposite side' in a right triangle?

Back

The side that is opposite to the angle of interest.

Front

What is the definition of 'hypotenuse' in a right triangle?

Back

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

Front

What does 'Soh Cah Toa' stand for?

Back

Soh: Sine = Opposite/Hypotenuse; Cah: Cosine = Adjacent/Hypotenuse; Toa: Tangent = Opposite/Adjacent.

Front

If the opposite side is 6 and the hypotenuse is 10, what is the sine of the angle?

Back

0.6 (Sine = Opposite/Hypotenuse = 6/10).

Front

If the adjacent side is 8 and the hypotenuse is 10, what is the cosine of the angle?

Back

0.8 (Cosine = Adjacent/Hypotenuse = 8/10).

Front

If the opposite side is 6 and the adjacent side is 8, what is the tangent of the angle?

Back

0.75 (Tangent = Opposite/Adjacent = 6/8).

Front

Solve for x: If sin(x) = 0.6, what is x?

Back

x ≈ 36.9°.

Front

Solve for x: If cos(x) = 0.8, what is x?

Back

x ≈ 36.9°.

Front

Solve for x: If tan(x) = 0.75, what is x?

Back

x ≈ 36.9°.
