x=a
x²- 3y²=0
(x-√3y)(x+√3y)=0
x=√3y.......(1)
x=-√3y.......(2)
x=a............(3)
Solve (1) and (2)√3y=-√3y, 2√3y=0,y=0
for y=0 x=0,
point is A (0,0)
solve (2) and (3)
y=-a/√3,
point B(a,-a/√3)
solve (3) and (1)
point C(a,a/√3)
Distance AB=√(a²+a²/3)=√4a²/3=2a/√3
BC=√(0²+4a²/3)=2a/√3
CA=√(a²+a²/3)=√(4a²/3)=2a/√3
SO ,AB =BC =CA EQUILATERAL TRIANGLE
