Geometrically, a triangle is NOT what we call a curve; so it does not have any particular [i]form[i] of equation. A triangle in a 2d plane is constructed by 3 straight lines, no two of which are parallel. Once you know the equations of those 3 straight lines, they represent a triangle.

**Any**equation in two dimensions represents a**curve**, not a figure like a triangle. You could, for example, write**three**equations representing the three sides of the triangle. - March 11th 2011, 06:44 AMSambit
