Determine the missing hypotenuse of a 45 45 90 triangle ex 2

The video tutorial explains how to find the missing legs of a 45-45-90 triangle. It covers the process of calculating the hypotenuse from a given leg by multiplying by the square root of 2, and conversely, finding a leg from the hypotenuse by dividing by the square root of 2. The tutorial also demonstrates how to rationalize the denominator to simplify expressions, ultimately providing a clear method to solve for the legs when given the hypotenuse.

What type of triangle is being discussed in the video?

• Scalene triangle

• Equilateral triangle

• 45-45-90 triangle

• 30-60-90 triangle

What operation is used to find the hypotenuse from a leg in a 45-45-90 triangle?

• Divide by sqrt 2

• Multiply by sqrt 2

• Multiply by 2

• Add 2

If given the hypotenuse, what operation is needed to find the leg in a 45-45-90 triangle?

• Multiply by sqrt 2

• Divide by sqrt 2

• Add sqrt 2

• Subtract sqrt 2

What is the purpose of rationalizing the denominator in this context?

• To change the triangle type

• To make the numerator a whole number

• To eliminate a radical in the denominator

• To simplify the expression

What is the final expression for the leg when the hypotenuse is given as 5 sqrt 2?

• 5

• 5 sqrt 2

• 5 / 2

• 5 sqrt 2 / 2
