You can put this solution on YOUR website!
Use the distance formula:
^2 + (y_1 - y_2)^2})
three times, once for each pair of points.
If you have 3 different distances, then the triangle is scalene.
If you have exactly two equal distances, then the triangle is isoceles.
If you have three equal distances, then the triangle is equilateral.
