I need to make some curved rafters for a verandah

roof.

The common rafters will be 1500mm when measured in a

straight line from the end points with a curve of

100mm, that is, the mid point of the curve will be

100mm from a straight line drawn from end to end, and

the curve will be part of a circle.

I need to know the curve for the rafters at each

corner of the verandah which are at 45deg.

The length is obviously 1500mm x sqrt2, but is the

curve 100mm x sqrt2?

I hope I've made it clear, and thanks in advance for

any help.
