Ricardo is constructing the inscribed circle for △ABC . He has already used his compass and straightedge to complete the part of the construction shown in the figure.Which construction could be his next step?Construct the angle bisector of ∠SBQ .Construct the angle bisector of ∠A .Construct the line through points A and R.Construct the perpendicular to BC⎯⎯⎯⎯⎯ through point R.

Given that Ricardo is constructing the inscribed circle for △ABC and he has already used his compass and straightedge to complete the part of the construction shown in the figure. For him to complete the construction he has to bisect at least two angle and he has only bisected one angle, Thus the correct answer among the choice given will be:

Construct the angle bisector of ∠A .
