Main Street Academy 2012-2013 Weekly Lesson Plan Format C.CLARK Course: Geometry Unit of Study: Unit 2: Introduction to Geometry Beginning Date: 09/18/12 Ending Date: 09/21/12 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.
