Day & Date: Monday 9-15-2014
Standard:
Understand similarity in terms of similarity transformations
MCC9-12.G.SRT.1
Verify experimentally the properties of dilations given by a center and a scale factor: a. A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged. b. The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
MCC9-12.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.
MCC9-12.G.SRT.3
Use the properties of similarity transformations to establish the AA criterion for two triangles to be similar.
Prove theorems involving similarity
MCC9-12.G.SRT.4
Prove theorems about triangles. Theorems include: a line parallel to one side of a triangle divides the other two proportionally, and conversely; the Pythagorean Theorem proved using triangle similarity.
MCC9-12.G.SRT.5
Use congruence and similarity criteria for triangles to solve problems and to prove relationships in geometric figures.
Prove geometric theorems
MCC9-12.G.CO.9
Prove theorems about lines and angles. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment’s endpoints.
Essential Question/Learning Goal:

What do I need to review in order to be successful on the Analytical Geometry Test?
Lesson Opener: (10 min.)
Watch iMovie of students completing station activities for similarity review.
Procedures/Strategies: (40 min.)

Individual work on study guide for Similarity Test.

Check answers using Aurasma


Lesson Summarizer: (5 min.) PMI Make a list of the things you did well on, things you still need to work on and what you think we should focus on tomorrow.
Assessment/Evaluation: Study Guide, discussion
Materials Needed: Calculator, iPad, Aurasma app, triggers
