 [RESOLVED] Pentagon Geometry Question
I have a board that is W inches wide, and I wish to cut from it a regular pentagon (sides of equal length) that has an altitude of W inches (the distance from a point to an opposite flat side.
Measured in terms of the width, W:
(1) How long (L) should the board be to cut the regular pentagon from it?
(2) What will be the length of each side, S?
(3) Assuming I can increase L, is this the largest regular pentagon that I can cut from a rectangular board of width W? My gut feeling is yes, but please advise.
