Question

16 multiple choice 1 point which of the following constructions must you know how to do in order to construct an inscribed circle for a given triangle? angle bisector duplicating a line segment bisecting a segment perpendicular bisector

Explanation:

The in - center of a triangle (center of the inscribed circle) is the point of intersection of the triangle's angle bisectors. So, to construct an inscribed circle for a given triangle, one must know how to construct angle bisectors. Duplicating a line segment, bisecting a segment, and constructing a perpendicular bisector are not directly related to finding the in - center.

Answer:

angle bisector
