Setting up Trig Ratios

Front

What is the definition of the Adjacent Side in a right triangle?

Back

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

Front

What is the definition of the Opposite Side in a right triangle?

Back

The side opposite the angle of interest.

Front

What is the definition of the Hypotenuse in a right triangle?

Back

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

Front

What is the sine function in trigonometry?

Back

The ratio of the length of the opposite side to the length of the hypotenuse (sin A = opp/hyp).

Front

What is the cosine function in trigonometry?

Back

The ratio of the length of the adjacent side to the length of the hypotenuse (cos A = adj/hyp).

Front

What is the tangent function in trigonometry?

Back

The ratio of the length of the opposite side to the length of the adjacent side (tan A = opp/adj).

Front

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

Back

Sine (sin).
