Calculations at a circular corner. Here, a circular corner is a right triangle, whose acute vertices are laid on a circle, so that the right angle is outside of that circle. The resulting circular segment is subtracted from the triangle. Enter two of the three lengths of the right triangle a, b and s, as well as the circle radius r. The radius must be larger than the chord length s. Choose the number of decimal places, then click Calculate. The angle is calculated and displayed in degrees. Calculations at a round corner, or rather in a quarter circle, the most simple form of a round corner. This is the intersecting set of a square with edge length a and a circle with radius a, where one corner of the square is at the center of the circle. The missing piece, the part of the square outside the quarter circle, is also called spandrel. Enter one value and choose the number of decimal places.
