Mark Central and Equidistant Points

What happens here

On the working line you just created, choose an arbitrary point where you want your perpendicular line to originate. Mark this point clearly with a small spray paint mark. This will be your central intersection point. Next, use your measuring tape to measure an equal distance from this central point in both directions along your working line. Mark these two new points. For instance, if you mark the center, measure 3 feet to the left and 3 feet to the right, marking both spots. The video visually demonstrates selecting a point and then measuring two equal distances from it.

Goal: Define key reference points on the working line.
