10-27-21 Lesson Plans for Honors Geometry

Standards Addressed

MGSE9-12.G.SRT.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.

MGSE9-12.G.SRT.3  Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar

MGSE9-12.G.SRT.5  Prove theorems about triangles: A line parallel to one side of a triangle divides the other two proportionally.

MGSE9-12.G.SRT.1  Verify experimentally the properties of dilations given by a center and a scale factor.
