Unit 4 Sem. 1 Review

Front

What is the relationship between the sides of a 45-45-90 triangle?

Back

In a 45-45-90 triangle, the lengths of the legs are equal, and the length of the hypotenuse is √2 times the length of a leg.

Front

What is the length of the hypotenuse in a 45-45-90 triangle if each leg is 4?

Back

The hypotenuse is 4√2.

Front

What is the length of the shorter leg in a 30-60-90 triangle if the longer leg is 10√3?

Back

The shorter leg is 10.

Front

What is the relationship between the angles in a 30-60-90 triangle?

Back

In a 30-60-90 triangle, the angles are 30°, 60°, and 90°.

Front

What is the length of the longer leg in a 30-60-90 triangle if the shorter leg is 5?

Back

The longer leg is 5√3.

Front

What is the formula to find the length of the hypotenuse in a right triangle?

Back

The hypotenuse can be found using the Pythagorean theorem: c² = a² + b².

Front

What is the value of x in a 45-45-90 triangle with legs of length 4?

Back

x = 4√2.

Front

What is the value of x in a 30-60-90 triangle if the shorter leg is 7?

Back

x (longer leg) = 7√3.

Front

What is the sum of the angles in any triangle?

Back

The sum of the angles in any triangle is always 180°.

Front

What is the value of x in a 30-60-90 triangle if the longer leg is 14?

Back

x (shorter leg) = 7.
