<PRE><B>Question 434559</B>
 I need help in finding the periminter of a triangle with the 3 points 
a. (-3,4) 
b. (3,-1)
c. (1,-2) 
----
a to b = sqrt[(4--1)^2+(-3-3)^2] = sqrt[25+36] = sqrt(61)
-------------
a to c = sqrt[(-2-4)^2+(1--3)^2] = sqrt[36+16] = sqrt(52)
-------------
b to c = sqrt[(-2--1)^2+(1-3)^2] = sqrt[1+4] = sqrt(5)
----
Add those to get the perimeter.
