Geometric Constructions 4-8
There is a difference between making a drawing and a geometric construction.
For drawings, we measure segments & angles using a ruler and a protractor to create our shapes or angles.
With geometric constructions, however, we only use a compass and a straight edge. Although we may use the ruler as our straight edge, we ignore the markings.
Construction 1: Bisect a Segment which also creates a 90 degree angle
Construction 2: Bisect an angle
Construction 3: Construct a 60 degree angle
Construction 4: Construct an angle congruent to a given angle.
