Standard(s) Taught

MAFS.912.G-CO.4.12

Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.  This includes: copying a segment, copying angle; bisecting a segment; bisecting an angle; constructing perpendicular lines, including the perpendicular bisector of a line segment; and constructing a line parallel to a given line through a point not on the line.)

MAFS.912.G-CO.4.13

Construct an equilateral triangle, a square, and a regular hexagon inscribed in a circle.
