#shorts • #reflection • #mathtricks • Learn the rule for reflecting figures in the y-axis on a coordinate plane. I will show you why the rule works (x, y) to (-x, y) for the image. No graph paper needed! • https://www.teacherspayteachers.com/S... • Common Core Math Standards • Understand congruence and similarity using physical models, transparencies, or geometry software. • 8.G.A.1 Verify experimentally the properties of rotations, reflections, and translations: • 8.G.A.1.A Lines are taken to lines, and line segments to line segments of the same length. • 8.G.A.1.B Angles are taken to angles of the same measure. • 8.G.A.1.C Parallel lines are taken to parallel lines. • 8.G.A.2 Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them. • 8.G.A.3 Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.
