Question 188504
<font face="Garamond" size="+2">


Use the distance formula:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  d = sqrt{(x_1 - x_2)^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.
