State competency goal and objective: G-CO.1KNOW precise definitions of angle, circle, perpendicular line, parallel line, and line segment, based on the
undefined notions of point, line, distance along a line, and distance around a circular arc.
G-CO.9 PROVE theorems about lines and angles. Theorems include: vertical angles ARE congruent; when a transversal CROSSES parallel lines, alternate
interior angles ARE congruent and corresponding angles ARE congruent; points on a perpendicular bisector of a line segment ARE exactly those equidistant
from the segment’s endpoints.
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.
