Find the perimeter of the triangle whose vertices are the following specified points in the plane.
(-3,-9),(10,-5) and (-9,8)
-----------------
Label the points
A(-3,-9), B(10,-5) and C(-9,8)
Find the length AB
---
s%5E2+=+diffy%5E2+%2B+diffx%5E2+=+4%5E2+%2B+13%5E2+=+185
AB+=+sqrt%28185%29
----------
Find BC and AC the same way, then add them.
Perimeter = the sum.
