Standard - GEO.G.CO.1:
Know precise definitions of angle, circle, perpendicular lines, parallel lines, and line segment, based on the undefined notions of point, line, distance along a line, and distance around a circular arc as these exist within a plane.

Standard - GEO.G.CO.2:
Represent transformations as geometric functions that take points in the plane as inputs and give points as outputs. Compare transformations that preserve distance and angle measure to those that do not.

Standard - GEO.G.CO.3:
Given a regular or irregular polygon, describe the rotations and reflections (symmetries) that map the polygon onto itself.

Standard - GEO.G.CO.4:
Develop definitions of rotations, reflections, and translations in terms of points, angles, circles, perpendicular lines, parallel lines, and line segments.

Standard - GEO.G.CO.5:
Given a geometric figure and a rotation, reflection, or translation, draw the transformed figure. Specify a sequence of transformations that will carry a given figure onto another.
