10-17-22 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.

Learning Targets/Success Criteria              

I can solve problems involving similar figures by

  -identifying similar figures

  -finding the scale factor of similar figures using ratios

  -setting up proportions to find missing side lengths of similar figures

  -prove two triangles congruent using triangle similarity theorems
