Meece Middle School
Mrs. Robin Crawford
Unit 11: Angles and Similarity
Class: Accelerated Math
Grade: 7 Days in Unit: 9 days
Objective:
Classify and determine the measures of angles, including angles created when parallels are cut by transversals.
Demonstrate that the sum of the angles in a triangle is 180 degrees and apply this fact to find unknown measures of
angles , and the sum of angles in polygons.
