Determine the missing lengths of a 45 45 90 triangle ex 1

This video tutorial explains how to find missing sides in a 45-45-90 special right triangle. It covers identifying the hypotenuse and calculating its length by multiplying a known leg by the square root of 2. The tutorial emphasizes that the legs of a 45-45-90 triangle are equal, simplifying the process of finding missing sides.

What is the first step in solving for missing sides in a 45-45-90 triangle?

• Find the perimeter

• Measure the angles

• Calculate the area

• Identify the hypotenuse

In a 45-45-90 triangle, what is true about the lengths of the legs?

• One leg is half the hypotenuse

• The legs are equal

• The legs are different

• One leg is twice the other

If one leg of a 45-45-90 triangle is 4, what is the length of the other leg?

• 6

• 4

• 8

• 2

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

• Multiply the leg by 2

• Multiply the leg by sqrt 2

• Add the leg to itself

• Divide the leg by sqrt 2

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

• 4

• 8

• 4 sqrt 2

• 2 sqrt 2
