West Virginia College and Career Readiness Standards
Understand congruence and similarity using physical models, transparencies, or geometry software.
M.8.16. Verify experimentally the properties of rotations, reflections and translations:
M.8.16.a. Lines are taken to lines, and line segments to line segments of the same length.
M.8.16.b. Angles are taken to angles of the same measure.
M.8.16.c. Parallel lines are taken to parallel lines.
WV.M.1HS8. 8th Grade High School Mathematics I
Congruence, Proof, and Constructions
Experiment with transformations in the plane.
M.1HS8.49. Know 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.
M.1HS8.50. Represent transformations in the plane using, example, transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).
