Is triangle ABC equilateral?
a) AB = 1
b) BC + AC = 2
AB = 1, BC = 0.75 and AC = 1.25 will be a valid triangle but not equilateral.
AB = 1, BC = 1 and AC = 1 will also be a valid triangle and equilateral.
Can you please explain E is the ans.
I think the ans is C because we can say that the triangle is equilateral with each side being 1. If the lengths of each side is not 1, then we cannot have a triangle.
