Can you explain please?

anonymous · Answer

just find the distance between every point

@divu.mkr I really don't understand, can you please show me an example?

The distance formula is $$d=\sqrt{(x_{2}-x_{1})^{2}+(y _{2}-y_{1})^{2}}$$
So what you can do is $$d=\sqrt{(2-8)^{2}+(6-2)^{2}}$$ And that would be the distance between point A and C. you applay the distance two times to the other points, (A and B, and B and C) and once you find the distance beween each sides, then you can determine what type of triangle it is.
