If three sides of a right triangle are 9, 40, and 41, which side is the hypotenuse?

• 9

• 40

• 41

Can side lengths 3, 4, and 5 form a right triangle?

Which equation can be used to solve the word problem: the diagonal of a t.v. is 40 inches and the height is 30. How wide is the t.v.?

• 30²  + 40² = c²

• a²  + 40² = 30²

• 30²  + b² = 40²

• 40²  + 30² = c²

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.

If the length of the hypotenuse in this triangle is 16, find the length of one leg.

• 8

• 32

If the length of the hypotenuse in this triangle is 7, find the length of the long side.
