Lesson 1-2 Practice

Which set of sides would make a right triangle?

• 4,5,6
• 8,10,12
• 5,12,13
• 5,10,12

What is the formula used to solve for the hypotenuse?

• a²⁺b²=c²
• a+b=c
• a-b=c
• c-a=c

Find the length of the missing side. 

• 25 cm
• 42 cm
• 52 cm
• 48 cm

solve for the value of y

• 13
• 5
• 23
• 10

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.

What is the length of y in this picture?

• 45
• 5√2
• 90
• 5

Which side is the short leg of this 30-60-90 triangle?

• 6
• m
• n

I have been given the short leg in this 30-60-90 triangle.  How do I find the long leg?

• Multiply 4 by 2
• Multiply 4 by √3
• Multiply 4 by √2
• Divide 4 by 2

I have been given the long leg in this 30-60-90 triangle.  How do I find the hypotenuse?

• Divide 8 by √3
• Divide 8 by 2
• Divide 8 by 2, then multiply that answer by √2
• Divide 8 by √3, then multiply that answer by 2
