3. a use the undefined notions of point, line, plane, and the concepts of distance along a line segment and distance around a circular arc to develop and use precise definitions and symbolic notations for angles and parts of lines to prove theorems and solve geometric problems (G.GSR.4.1)
3. c make formal geometric constructions with a variety of tools and methods (i.e., copy a segment and an angle, bisect a segment and an angle, construct the perpendicular bisector of a line segment, construct perpendicular lines, and construct a line parallel to a given line through a point not on the line) (G.GSR.4.3)
