I have to replace the moulding on a door. The door has two quarter
lites at the top, and these lites are curved. I am curious how to
calculate the angle that the mitre would need to be.

Any ideas? Is there a rule of thumb?


I am thinking it would still be a 45 degree miter where the curve meets the
straight if the 1/4 lites are 1/4 circles. On a 1/4 circle the arc
intersects the vertical or horizontal at a right angle.
