MGSE.9-12.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 they equality of all corresponding angles and the proportionality of all corresponding pairs of sides.


Learning Targets /Success Criteria:
--I can identify the corresponding sides and angles of similar figures.
--I can set up ratio and proportions of corresponding side lengths and angle measures.
--I can solve problems involving similar figures by setting up and solving ratios and proportions and simplifying ratios.


Introduction/Connection (Bellringer) students will complete #1a-f on Similarity/Geometric Relationships handout (attached below as Similarity Review).


Direct Instruction/Guided Practice:
--Review bellringer
--Guide students in completing Similar Polygons foldable (attached below).
--Similar Polygons worksheet (attached)


Differentiation/Independent Practice/Collaboration:
--Differentiation; Foldable, cloze notes, graphic organizers, one-on-one assistance for struggling students, accelerated problems for more advanced students.
--Independent Practice/Collaboration: students will work in pairs to complete Similar Polygons w/s


Summarizer/CFU: Students will identify and set up ratios and proportions to solve problems involving similar polygons.


Assignment: Students will complete all of Similar Polygons practice ws (attached below).
