Answer variants:
Draw a line segment \(AB = 3.1\) \(cm\).
Join \(AC\) and \(BC\) to get the required triangle \(ABC\).
Now, with \(B\) as centre, construct another arc of radius \(3.1\) \(cm\) such that it cuts the previous arc at \(C\).
With \(A\) as centre, construct a sufficiently long arc of radius \(3.1\) \(cm\).
Arrange the procedure in a correct sequence to construct a triangle in which all the sides are of length \(3.1\) \(cm\) more efficiently.
