Unit #1: Congruence, Proof, and ConstructionContent Area:MathematicsCourse(s):Generic CourseTime Period:Marking Period 1Length:4 weeksStatus:PublishedStandardsMA.9-12.G-CO.A.1Know precise definitions of angle, circle, perpendicular line, parallel line, and linesegment, based on the undefined notions of point, line, distance along a line, anddistance around a circular arc.MA.9-12.G-CO.A.2Represent transformations in the plane using, e.g., transparencies and geometrysoftware; describe transformations as functions that take points in the plane asinputs and give other points as outputs. Compare transformations that preservedistance and angle to those that do not (e.g., translation versus horizontalstretch).MA.9-12.G-CO.A.5Given a geometric figure and a rotation, reflection, or translation, draw thetransformed figure using, e.g., graph paper, tracing paper, or geometry software.Specify a sequence of transformations that will carry a given figure onto another.
