Points on a plane and finding perimeter

[WriterGirl]

Points D(-4, 6), E(5, 3), and F(3, -2) are the vertices of triangle DEF. Find the perimeter of the triangle.

There is no picture for this assignment but I drew one on graph paper.

I have no clue where to start.

Thanks

Hmm... It sounds like they forgot to cover the Distance Formula before they assigned questions on it! :shock:

Plug the pairs of points into the Distance Formula to find the length of each side. Then add the three lengths to find the perimeter.

If you get stuck, please reply showing all of your steps and reasoning. Thank you!
