What is the hypotenuse in a right triangle?

Back

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

How do you find the length of a side using the sine ratio?

Back

To find the length of a side using the sine ratio, use the formula: length of opposite side = hypotenuse * sin(angle).

Front

How do you find the length of a side using the cosine ratio?

Back

To find the length of a side using the cosine ratio, use the formula: length of adjacent side = hypotenuse * cos(angle).

Front

How do you find the length of a side using the tangent ratio?

Back

To find the length of a side using the tangent ratio, use the formula: length of opposite side = adjacent side * tan(angle).

What is the inverse sine function?

Back

The inverse sine function, denoted as sin^(-1) or arcsin, is used to find the angle when the sine value is known.

Front

What is the inverse cosine function?

Back

The inverse cosine function, denoted as cos^(-1) or arccos, is used to find the angle when the cosine value is known.
