Front

Identify the sides of a right triangle: opposite, adjacent, and hypotenuse.

Back

In a right triangle, the hypotenuse is the longest side opposite the right angle, the opposite side is opposite the angle of interest, and the adjacent side is next to the angle of interest.

How do you find the opposite side using the sine ratio?

Back

To find the opposite side, use the formula: opposite = hypotenuse * sin(angle).

Front

How do you find the adjacent side using the cosine ratio?

Back

To find the adjacent side, use the formula: adjacent = hypotenuse * cos(angle).

Front

How do you find the hypotenuse using the sine ratio?

Back

To find the hypotenuse, use the formula: hypotenuse = opposite / sin(angle).

Front

How do you find the opposite side using the tangent ratio?

Back

To find the opposite side, use the formula: opposite = adjacent * tan(angle).

Front

How do you find the adjacent side using the tangent ratio?

Back

To find the adjacent side, use the formula: adjacent = opposite / tan(angle).
