Ch 6.1 Review

In this 45-45-90 triangle, if the length of one leg is 5 units find the other leg.

• Multiply that leg by 2, so y=10

• Use the same length for the given leg to find y, so y=5

• Multiply that leg by √2, so y=5√2

• Divide that leg by √2, so y= 5/√2

In this 45-45-90 triangle, I have been given the length of a leg.  How do I find the length of the hypotenuse?

• It is the same length as the given leg.
• Multiply that leg's length by √2.
• Multiply that leg's length by 2.
• Divide that leg's length by √2.

I have been given a hypotenuse in this 45-45-90 triangle.  How do I find the length of a leg of the triangle?

• Multiply by √2
• Divide by √2
• It's the same length as the hypotenuse.
• Divide by 2
