[G.CO.12] Congruence #12

Objective

Common Core Text:

• [G.CO.12] Make formal geometric constructions with a variety of tools and methods (compass and straightedge, string, reflective devices, paper folding, dynamic geometric software, etc.).

  • Copying a segment;

  • copying an 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.
