Trig Ratios-Finding missing sides and angles.

Front

What are the three primary trigonometric ratios?

Back

Sine (sin), Cosine (cos), and Tangent (tan).

Front

Define Sine (sin) in terms of a right triangle.

Back

Sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

Define Cosine (cos) in terms of a right triangle.

Back

Cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

Define Tangent (tan) in terms of a right triangle.

Back

Tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.

How do you find the missing side of a right triangle using trigonometric ratios?

Back

Use the appropriate trigonometric ratio (sin, cos, or tan) based on the known angle and side.
