Impossible Constructions?Date: 04/08/97 at 22:14:35 From: Josh Steffenson Subject: Impossible Constructions My geometry teacher told us there were 3 impossible problems/ constructions, one of which is trisecting an angle. What are the other two? Thanks, Josh Steffenson Date: 04/09/97 at 11:45:16 From: Doctor Wilkinson Subject: Re: Impossible Constructions The other two are (2) Duplicating the cube: given the side of a cube, construct the side of a cube with twice the volume (3) Squaring the circle: given the radius of a circle, construct the side of a square with the same area as the circle with the given radius. -Doctor Wilkinson, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
