2014-2015 MATH Instructional Curriculum Plan Weeks of: Feb. 2- Feb. 13 Grade: 9-12 Unit 6: Polygons Geometry: Congruence Standards Geometry: Congruence Access Points MACC.912.G-CO.1.1. 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. MAFS.912.G-CO.1.AP.1a Identify 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. MACC.912.G-CO.1.2 Represent transformations in the plane using, e.g., 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). MAFS.912.G-CO.1.AP.2a Represent transformations in the plane using, e.g., transparencies and geometry software. MAFS.912.G-CO.1.AP.2b Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch). MACC.912.G-CO.1.3 Given a rectangle, parallelogram, trapezoid or regular polygon, describe the rotations and reflections that carry it onto itself. MAFS.912.G-CO.1.AP.3a Describe the rotations and reflections of a rectangle, parallelogram, trapezoid, or regular polygon that maps each figure onto itself. MACC.912.G-CO.1.4 Develop definitions of rotations, reflections and translations in terms of angles, circles, perpendicular lines, parallel lines and line segments. MAFS.912.G-CO.1.AP.4a Using previous comparisons and descriptions of transformations, develop and understand the meaning of rotations, reflections, and translations based on angles, circles, perpendicular lines, parallel lines, and line segments. MACC.912.G-CO.1.5 Given a geometric figure and a rotation, reflection or translation, draw the transformed figure using, e.g., graph paper, tracing paper or geometry software. Specify a sequence of transformations that will carry a given figure onto another. MAFS.912.G-CO.1.AP.5a Transform a geometric figure given a rotation, reflection, or translation using graph paper, tracing paper, or geometric software. MAFS.912.G-CO.1.AP.5b Create sequences of transformations that map a geometric figure on to itself and another geometric figure. MACC.912.G-CO.2.6 Use geometric descriptions of rigid motions to transform figures and to predict the effect of a given rigid motion on a given figure; given two figures, use the definition of congruence in terms of rigid motions to decide if they are congruent. MAFS.912.G-CO.2.AP.6a Use descriptions of rigid motion and transformed geometric figures to predict the effects rigid motion has on figures in the coordinate plane. MACC.912.G-CO.2.7 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. MAFS.912.G-CO.2.AP.7a Use definitions to demonstrate congruency and similarity in figures. MACC.912.G-CO.2.8 Explain how the criteria for triangle congruence angle-side-angle (ASA), side-angle-side (SAS), MAFS.912.G-CO.2.AP.8a Use the definition of congruence, based on rigid motion, to develop and MAFS.912.G-CO.2.AP.6b Knowing that rigid transformations preserve size and shape or distance and angle, use this fact to connect the idea of congruency and develop the definition of congruent. 2014-2015 MATH Instructional Curriculum Plan Weeks of: Feb. 2- Feb. 13 Grade: 9-12 Unit 6: Polygons side-side-side (SSS) and hypotenuse-leg follow from the definition of congruence in terms of rigid motions. Geometry: Similarity, Right Triangles & Trigonometry Standards explain the triangle congruence criteria; ASA, SSS, and SAS. Geometry: Similarity, Right Triangles & Trigonometry Standards MACC.912.G-SRT.1.2 Given two figures, use the definition of similarity in terms of similarity transformations to decide if they are similar; explain using similarity transformations the meaning of similarity for triangles as the equality of all corresponding pairs of angles and the proportionality of all corresponding pairs of sides. MAFS.912.G-SRT.1.AP.2a Determine if two figures are similar. MACC.912.G-SRT.1.3 Use the properties of similarity transformations to establish the angle-angle (AA) criterion for two triangles to be similar. MAFS.912.G-SRT.1.AP.3a Apply the angle-angle (AA) criteria for triangle similarity on two triangles. MACC.912.G-SRT.2.4 Prove theorems about triangles. Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity. MAFS.912.G-SRT.2.AP.4a Establish facts about the lengths of segments of sides of a triangle when a line parallel to one side of the triangles divides the other two sides proportionally. MACC.912.G-SRT.2.5 Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures. MAFS.912.G-SRT.2.AP.5a Apply the criteria for triangle congruence and/or similarity (angle-sideangle [ASA], side-angle-side [SAS], side-side-side [SSS], angle-angle [AA] to determine if geometric shapes that divide into triangles are or are not congruent and/or can be similar. Geometry: Modeling with Geometry Standards MACC.912.G-MG.1.1 Use geometric shapes, their measures, and their properties to describe objects (e.g., modeling a tree trunk or a human torso as a cylinder). MAFS.912.G-SRT.1.AP.2b Given two figures, determine whether they are similar and explain their similarity based on the equality of corresponding angles and the proportionality of corresponding sides. Geometry: Modeling with Geometry Standards MAFS.912.G-MG.1.AP.1a Describe the relationship between the attributes of a figure and the changes in the area or volume when one attribute is changed.
