Hypotenuse, Opposite, or Adjacent

Front

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 opposite side in relation to an angle in a right 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 right triangle?

Back

The adjacent side is the side that is next to the angle in question, but not the hypotenuse.

Front

In a right triangle, if one angle is 30 degrees, what is the relationship between the sides?

Back

The side opposite the 30-degree angle is half the length of the hypotenuse.

Front

If the hypotenuse of a right triangle is 10 units, what is the maximum possible length of the opposite side?

Back

The maximum length of the opposite side is 10 units, which occurs when the angle is 90 degrees.

Front

What is the Pythagorean theorem?

Back

Front

If the lengths of the two legs of a right triangle are 3 and 4, what is the length of the hypotenuse?

Back

Front

What is the sine of an angle in a right triangle?

Back

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

Front

What is the cosine of an angle in a right triangle?

Back

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

Front

What is the tangent of an angle in a right triangle?

Back

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