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

Back

The opposite side is the side opposite to the angle being considered.

Front

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

Back

The adjacent side is the side next to the angle being considered, excluding the hypotenuse.

What does the acronym SOHCAHTOA stand for?

Back

SOHCAHTOA helps remember the definitions of sine, cosine, and tangent: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.

Front

How do you find the sine of an angle in a right triangle?

Back

To find the sine of an angle, divide the length of the opposite side by the length of the hypotenuse.

Front

How do you find the cosine of an angle in a right triangle?

Back

To find the cosine of an angle, divide the length of the adjacent side by the length of the hypotenuse.

Front

How do you find the tangent of an angle in a right triangle?

Back

To find the tangent of an angle, divide the length of the opposite side by the length of the adjacent side.
