Which of the following correctly labels the legs and hypotenuse of this right triangle?

• EF and EG are legs

  FG is the hypotenuse

• FG and EG are legs

  EF is the hypotenuse

• EF and FG are legs

  EG is the hypotenuse

• This is not a right triangle.

What is the approximate length of the hypotenuse of triangle EFG?

• 9.0 units

• 10.0 units

• 13.5 units

• 14.6 units

The points P(-3, -2), Q(10, -2), and R(3, -8) are the vertices of a triangle. What is the approximate perimeter of the triangle?

• 9 units

• 22 units

• 35 units

• 13 units

Answer explanation

This is a picture of the three points plotted. See how they create a right triangle. Counting the places between P and R is 6, between P and Q is 7. Use these to find the length of RQ, which is 9.2.

Add up all three values to find the perimeter!
