Confirm Accuracy with Speed Square

What happens here

To confirm the accuracy of the drawn line, take a speed square and align its 90-degree corner with the corner of your plywood where the 45-degree line originates. Position the speed square so that its 45-degree mark aligns with your drawn line. The video demonstrates this, showing that the line perfectly matches the 45-degree indicator on the speed square, confirming the method's precision.

Goal: Verify that the drawn line is precisely 45 degrees.
