do you know the distance formula? to find the distance between 2 points...simply use it to find the distances between the three points and add those three distances together... distance formula distance = $$\sqrt{(x _{1}-x _{2})^{2}+(y _{2}-y _{1})^{2}}$$ the following link may be helpful... http://www.purplemath.com/modules/distform.htm
