Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the side opposite the right angle and is the longest side of a right triangle.

Front

What is the opposite side in relation to an angle in a triangle?

Back

The opposite side is the side that is directly across from the angle in question.

Front

What is the adjacent side in relation to an angle in a triangle?

Back

The adjacent side is the side that forms the angle with the hypotenuse.

Front

How do you calculate the sine of an angle?

Back

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

Front

How do you calculate the cosine of an angle?

Back

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

Front

How do you calculate the tangent of an angle?

Back

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