This week in Geometry we will be using a compass and straightedge to perform the six basic constructions: 1) Copying a line segment 2) Copying an angle 3) Creating a perpendicular bisector 4) Creating an angle bisector 5) Creating parallel lines 6) Creating a perpendicular line through a given point When creating a perfect construction no numbers are involved.  We do not measure, but rather we mark off distance by creating arcs (or congruent circles) using a compass. There are many videos on you tube that demonstrate each construction. For an animated tutorial: Click here  or go to http://www.mathsisfun.com/geometry/constructions.html   … [Read more...]
