Intro to Trig-Labeling Sides, choosing trig function pre

Front

What is the longest side of a right triangle called?

Back

Hypotenuse

Front

Which trigonometric function is used when you have the adjacent side and the hypotenuse?

Back

Cosine

Front

From angle C in a right triangle, which side is opposite to angle C?

Back

Opposite

Front

What is the side called that is next to the angle in a right triangle?

Back

Adjacent

Front

Which trigonometric function is used when you have the opposite side and the hypotenuse?

Back

Sine

Front

What is the formula for the tangent function in a right triangle?

Back

Tan(θ) = Opposite / Adjacent

Front

If you know the lengths of the opposite and adjacent sides, which function would you use to find the angle?

Back

Tangent

Front

What is the relationship between sine, cosine, and tangent in a right triangle?

Back

Sine = Opposite / Hypotenuse, Cosine = Adjacent / Hypotenuse, Tangent = Opposite / Adjacent

Front

In a right triangle, if the hypotenuse is 10 and the opposite side is 6, what is the sine of the angle?

Back

Sine = 6/10 = 0.6

Front

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

Back

Cosine = 8/10 = 0.8
