Determine the missing hypotenuse of a 45 45 90 triangle ex 3

The video tutorial explains the properties of a 45-45-90 right triangle, highlighting that the legs are equal and the hypotenuse is calculated by multiplying the leg by the square root of 2. The tutorial provides a step-by-step guide to determine the hypotenuse when one leg is known, using an example where the leg is the square root of 7, resulting in a hypotenuse of the square root of 14.

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

• They are equal in length.

• One is twice the length of the other.

• They are different lengths.

• They form a 60-degree angle.

In a 45-45-90 triangle, where is the hypotenuse located?

• Adjacent to the 45-degree angle.

• Next to the longest leg.

• Opposite the 45-degree angle.

• Directly across from the 90-degree angle.

If one leg of a 45-45-90 triangle is sqrt 7, what is the length of the other leg?

• 14

• sqrt 14

• 7

• sqrt 7

How do you calculate the hypotenuse in a 45-45-90 triangle if one leg is known?

• Add the leg to sqrt 2.

• Multiply the leg by sqrt 2.

• Multiply the leg by 2.

• Multiply the leg by sqrt 3.

What is the final expression for the hypotenuse if the leg is sqrt 7?

• sqrt 14

• sqrt 49

• sqrt 9

• sqrt 21
