Denise is constructing a square in which two of its vertices are points \( M \) and \( N \). She has already used her straightedge and compass to construct the lines and arcs shown. What should Denise do for her next step? Place the point of the compass on point \( M \) and draw any arc above it. Use a straightedge to draw Place the point of the compass on point \( N \) and draw an arc that intersects width for the opening of the compass. Use a straightedge to draw a horizontal line that contains point \( O \).
