# Thread: perimeter of triangle, given coordinates of vertices

1. ## perimeter of triangle, given coordinates of vertices

I need help in solving this. I did the points and got the triangle, but confused on how to find the perimeter of this triangle. Here is the problem:

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

2. ## Re: perimeter of a triangle confused

Find the lengths of line segments joining (D,E), (E,F) & (F,D) - using the distance formula.

Then add those up - very straight forward.
