Similarity (Day 2)

50 Minute Class, Curriculum, Geometry

Learning Goal: Develop understanding of what it means for polygons to be similar and solve application problems.


Classwork

 Standards:

  • Common Core
    • HSG.SRT.A – Understand similarity in terms of similarity transformations
    • HSG.SRT.B.5 – Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
  • TEKS
    • G.7(A) – apply the definition of similarity in terms of a dilation to identify similar figures and their proportional sides and the congruent corresponding angles
    • G.7(B) – apply the Angle-Angle criterion to verify similar triangles and apply the proportionality of the corresponding sides to solve problems
