This document provides steps to construct an ogee curve using parallel lines and perpendicular bisectors. First, two parallel lines are drawn. Then perpendicular bisectors are drawn to bisect the lines. The intersection of the perpendicular bisectors is the center of the required tangent arcs that form the ogee curve.

1. Ogee Curve

2. Step 1 Let NA and BM be the two parallel lines.

3. Step 2

4. Step 3 Draw perpendicular bisectors

5. Step 4 The intersection of F and C of these bisectors and perpendiculars respectively, are the centers of required tangent arcs.

6. Step 5
