Place the point of the compass on point Q and draw an arc that intersects the first arc, using the same width for the opening of the compass as the first arc.
Step-by-step explanation:
She is constructing an equilateral triangle. This means that all 3 sides must be congruent. She has drawn an arc by placing her compass on point P and setting it to the width of segment PQ. This arc passes through point Q.
In order to ensure that the sides are congruent, she must keep her compass the same width. She will now go to the opposite end of the segment, point Q, and construct an arc that runs through point P. The goal is to intersect her first arc at a point that will serve as the third vertex of the triangle.
