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.
Learning Targets/Success Criteria
I can solve problems involving similarity by:
finding scale factors
AA triangle similarity postulate
SSS triangle similarity theorem
SAS triangle similarity theorem
triangle proportionality theorem
Direct Instruction/Guided Practice
discuss Pythagorean Theorem
Monitoring students throughout lesson as some students will work individually and some will work with partners. Some students will work ahead on additional assignments or enrichment activities.
Summarize/Check for Understanding
Teacher questioning for understanding/clarification.
Guided practice will be checked for accuracy and corrections will be made.
