Question

Which construction must you do to construct a triangle given the lengths of two sides and the measure of the angle between the two sides? A) Construct a 90° angle. B) Construct a line parallel to a given line. C) Construct an angle congruent to a given one. D) Construct a line perpendicular to a given line.

Answer 1

The goal is to construct a triangle. If you choose A) you will only have two lines connecting, with an angle of 90°. If you choose B) you cannot have a triangle also with 2 lines only. Neither D). So choose C) construct an angle congruent to a given one-- connect the lines and produce a perfect triangle.
