A triangle has a perimeter of exactly 24 units. Which of the following could be the vertices of the triangle?

> (-1,3),(2,-1),(-1,-1)
(6,0),(6,7),(0,7)
(-1,-1),(-6,-13),(-9,-9)
(-3,-4),(3,-4),(3,4)

Your choice has sides 3,4,5 whose sum is 12

If you can find vertices making sides of 6,8,10 then that will work. Luckily it is a right triangle, with a horizontal side and a vertical side. It's easiest if you plot the points on graph paper.
