Well, First use a graph and plot the vertices. then count that blocks on the outside of the triangle. This is the perimeter. A good way to remember is peRIMeter.

Find the perimeter of the triangle with the vertices at
(1, 2), (-6, 5), and (-6, -4).
---------------
Use the distance formula to find the 3 side lengths.
Perimeter = the sum of the 3 lengths.

Find the perimeter of the triangle with the vertices at
(1, 2), (-6, 5), and (-6, -4).
You need to use the distance formula to find the length of the line connecting points (1, 2) & (- 6, 5), and (1, 2) & (- 6, - 4). 

You do not need to do this for the line connecting (- 6, 5) and (- 6, - 4) since these points' x-coordinates are the same, hence a vertical line
that's parallel to the y-axis. This length is found by merely taking the absolute value of the difference between the y-coordinates.
This is: either: abs%285+-+-+4%29, or abs%28-+4+-+5%29. You could also subtract the smaller value (- 4) from the larger value (5).
Do you now see the length of this side? I sure hope so!
