Front

What is the property of the legs in a 45-45-90 triangle?

Back

In a 45-45-90 triangle, the lengths of the legs are equal.

Front

How do you find the hypotenuse in a 45-45-90 triangle?

Back

Multiply the length of a leg by √2.

Front

What is the sine ratio for 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 ratio for 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

In a 30-60-90 triangle, what is the relationship between the short leg and the hypotenuse?

Back

The hypotenuse is twice the length of the short leg.

Front

How do you find the length of the long leg in a 30-60-90 triangle?

Back

Multiply the length of the short leg by √3.

Front

What is the sine of 33 degrees in terms of a right triangle?

Back

sin(33) = opposite/hypotenuse.

Front

What is the cosine of 33 degrees in terms of a right triangle?

Back

cos(33) = adjacent/hypotenuse.

Front

If the short leg of a 30-60-90 triangle is 4, what is the length of the hypotenuse?

Back

The hypotenuse is 8.

Front

If the short leg of a 30-60-90 triangle is 4, what is the length of the long leg?

Back

The long leg is 4√3.
