What is the hypotenuse in a right triangle?

Back

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

Front

What is the side opposite angle X in a right triangle?

Back

The side opposite angle X is the side that does not touch angle X.

Front

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

Back

Cosine of an angle = length of adjacent side / length of hypotenuse.

Front

What equation represents the sine function in a right triangle?

Back

Sin(θ) = opposite side / hypotenuse.

Front

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

Back

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

Front

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

Back

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

Front

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

Back

Tangent of an angle = length of opposite side / length of adjacent side.

Front

What is the Pythagorean theorem?

Back

In a right triangle, a² + b² = c², where c is the hypotenuse.

Front

What is the relationship between sine, cosine, and tangent?

Back

Tan(θ) = Sin(θ) / Cos(θ).

Front

How do you solve for a side using the sine function?

Back

Use the equation Sin(θ) = opposite / hypotenuse and rearrange to find the unknown side.
