Draw Straight Line

What happens here

Once the initial mark is made, the carpenter demonstrates a clever trick: he positions the tape measure so that the end of its metal hook is flush with the edge of the board. He then pivots the tape measure tape itself around the initial mark, keeping the tape's edge aligned with the mark. With the tape acting as a straight edge, he draws a straight line using his pencil, extending from one edge of the board to the other. This method quickly creates a precise, straight cut line.

Goal: To draw a straight line perpendicular to the edge, pivot the tape measure from the marked point, aligning the tape's edge with the marked point and ensuring the tape itself remains straight.
