To construct the angle bisector of angle LPQR after drawing the initial arc from point Q that intersects the sides of the angle at points P and R, the next essential step is to place the pointed end of the compass on point P and draw another arc that intersects the first arc.
The correct option is:
Option #2: Place the pointed end of the compass on point P and draw another arc inside the first arc and between the two sides of the angle.
This arc will then be used to intersect with an arc drawn from point R, allowing you to find the point that is equidistant from both sides of the angle. This intersection will then be used to draw the bisector line, completing the construction.
