There are threw pts using three pts find three equation of lines then find the angle,between two lines it will be 60 degree After this consider another combinations of the lines and find the angle berserk them it will be 60 degree as two angles of the triangle,is 60 so last qngle will also be 60 and hence,given triangle,is equilateral. Tan(a)=|m1-m2|/[1+m1*m2] a= angle b/w two lines,m1=slope of one line,m2= slope of other
