Final answer:
The bisector of ∠pqr is a line or ray that divides the angle into two equal parts.
Step-by-step explanation:
The bisector of ∠pqr is the line or ray that divides the angle into two equal parts. It passes through the vertex of the angle and divides it into two congruent angles. To find the bisector of ∠pqr, we can construct an angle bisector using a compass and a straightedge. Start by drawing an arc from point p that intersects both rays pq and pr. Then, draw an arc from point r that intersects both rays rq and rp. The point where the two arcs intersect is the vertex of the angle bisector.
