Grade 8 Unit 3 Congruence and Similarity Assessment Plan Understand congruence and similarity using physical models, transparencies, or geometry software. 8. G.1: Verify experimentally the properties of rotations, reflections, and translations. a. Lines are taken to lines, and line segments to line segments of the same length. b. Angles are taken to angles of the same measure. c. Parallel lines are taken to parallel lines. 8. G.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.3: Describe the effect of dilations, translations, rotations, and reflections on twodimensional figures using coordinates. 8. G.4: Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two dimensional figures, describe a sequence that exhibits the similarity between them. 8. G.5: Use informal arguments to establish facts about the angle sum and exterior angle of triangles, about the angles created when parallel lines are cut by a transversal, and the angleangle criterion for similarity of triangles. Unit Supporting Standards (Supporting standards should be used to create a context for Unit Standards, and should not be explicitly taught) Analyze and solve linear equations and pairs of simultaneous linear equations. 8. F.1: Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. 8. EE.7 Solve linear equations in 1 variable (PBA: Type 1) 1 Transfer: Students will apply concepts and procedures regarding functions to represent, describe and interpret transformations on geometric figures. Students will apply concepts of angle congruence in solving problems involving geometric figures in the plane. Ex: Prove the sum of angles in a triangle using alternate interior and alternate exterior angles. Ex: Give a function rule that takes an input of a point on the coordinate plane and fives an output of a point that is a rotation about the origin by 90 of the input.
