Chapter 6 Alignment to Core Standards:
Domain G.CO.A.4: Develop definitions of rotations, reflections, and translations in terms of angles,
circles, perpendicular lines, parallel lines, and line segments.
Domain G.CO.B.7: Use the definition of congruence in terms of rigid motions to show that two triangles
are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are
congruent.
Domain G.CO.B.8: Explain how the criteria for triangle congruence follow from the definition of
congruence in terms of rigid motions.
Domain G.CO.C.10: Prove theorems about triangles.
Domain G.CO.12: Make geometric constructions.
Domain HSG.GPE.B.7: Use coordinates to prove simple geometric theorems algebraically. Use
coordinates to compute perimeters of polygons and areas of triangles and rectangles, e.g., using the
distance formula.
