Front

What is the hypotenuse in a right triangle?

Back

The hypotenuse is the side opposite the right angle.

Front

What is the sine ratio in a right triangle?

Back

The sine ratio is defined as 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 defined as 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 defined as the ratio of the length of the opposite side to the length of the adjacent side.

Front

How do you find the missing angle in a right triangle?

Back

Use the sine, cosine, or tangent ratios to set up an equation and solve for the angle.

Front

If one angle in a right triangle is 38 degrees, what is the other non-right angle?

Back

The other angle is 52 degrees, since the sum of angles in a triangle is 180 degrees.
