Sine/Cosine/Tangent practice HW

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is the ratio of the length of the opposite side to the length of the hypotenuse.

Front

What is the cosine ratio in a right triangle?

Back

The cosine ratio is the ratio of the length of the adjacent side to the length of the hypotenuse.

Front

What is the tangent ratio in a right triangle?

Back

The tangent ratio is the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you find the sine of an angle?

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?

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?

Back

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

Front

What is the Pythagorean theorem?

Back

In a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²).

Front

What is the opposite side in a right triangle?

Back

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

Front

What is the adjacent side in a right triangle?

Back

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

Front

What is the hypotenuse in a right triangle?

Back

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