Outcomes

G.G-CO.D.12

Make formal geometric constructions with a variety of tools and methods. Constructions include: copying segments; copying angles; bisecting segments; bisecting angles; 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.

G.G-SRT.B.5

Use congruence and similarity criteria to prove relationships in geometric figures and solve problems utilizing real-world context.
