What should Carlotta do for her next step? is constructing an equilateral triangle. She has already constructed the line segment and arc shown.
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 intersects the first arc, using the same width for the opening of the compass as the first arc.
Use the straightedge to draw a line that passes through point \( Q \) and intersects the arc.
Place the point of the compass on point \( Q \) and draw opening of the compass that is less than \( \frac { 1 } { 2 } P Q .\)
