The vertices of a triangle are A(–1, 3), B(–2, 2) and C(3, –1). A new triangle is formed by shifting the sides of the triangle by one unit inwards. Then the equation of the side of the new triangle nearest to origin is :
1
x - y - (2 + √2) = 0
2
-x + y - (2 - √2) = 0
3
x + y - (2 - √2) = 0
4
x + y + (2 - √2) = 0
