While you may push away the day's ennui with a competitive session of Minecraft Bed Wars, the ancient Greeks whiled away the minutes by constructing complex geometric figures using only a compass and a straightedge.  In fact, they made a bit of game of it, and this lesson presents the rules of that game.

Geometry 4(A) Distinguish between undefined terms, definitions, postulates, conjectures, and theorems

Geometry 5(B) construct congruent segments, congruent angles, a segment bisector, an angle bisector, perpendicular lines, the perpendicular bisector of a line segment, and a line parallel to a given line through a point not on a line using a compass and a straightedge

Geometry 5(C) use the constructions of congruent segments, congruent angles, angle bisectors, and perpendicular bisectors to make conjectures about geometric relationships
