## What is the radius of curvature of a circle?

In differential geometry, the radius of curvature, R, is the reciprocal of the curvature. For a curve, it equals the radius of the circular arc which best approximates the curve at that point. For surfaces, the radius of curvature is the radius of a circle that best fits a normal section or combinations thereof.

## What is the diamond in a speed square for?

Other Cool Features – The Swanson Speed Square has a patented feature — the diamond cut, a diamond-shaped cut-out on the ruler edge of the tool. This is used for squaring on a line scribed across the board so that you can then make a perfect 90° line from your scribed angled to the edge of the board.
