**Damon**, Thursday, January 24, 2008 at 7:36pmwhat are the lengths of the sides?

If they are all different, it is scalene.

You can just do the squares of the lengths, no need to take the square roots.

in general:

length^2 = (X2-X1)^2 + (Y2-Y1)^2

**Damon**, Thursday, January 24, 2008 at 7:59pmfor example the length from X to Y:

XY^2 = (2 - -3)^2 + (4 - 1)^2

= 5^2 + 3^2

= 25 + 9

= 34 is the square of length XY
