What happens here

Locate the exact intersection points of the arcs you just drew – the center of the 'X' above the working line and the center of the 'X' below the working line. Use a straight edge, such as a string line pulled taut between two stakes, or simply connect the marks by eye if precision allows, and use your spray paint wand to draw a straight line connecting these two intersection points. This new line will pass directly through your initial central intersection point on the working line and will be perfectly perpendicular (at a 90-degree angle) to it. The video clearly shows connecting the two 'X' marks with a straight line, confirming it forms a 90-degree angle.

Goal: Establish a true 90-degree line to the working line.

>> And this is your 90°. You can measure off all this for any walls, foundation, in either way. Thanks for watching.
