Carlotta is constructing an equilateral triangle. She has already constructed the line segment and arc shown. What should Carlotta do for her next step? Use the straightedge to draw a line that passes through point Q and intersects the arc. O Use the straightedge to draw a line that passes through point P and intersects the arc. Place the point of the compass on point Q and draw O an arc that intersects the first arc, using the same width for the opening of the compass as the first arc. Place the point of the compass on point Q and draw an arc that intersects the first arc, using a width for the opening of the compass that is less than ~ P
