1. The document outlines the assignments and lesson topics for lesson 18, including setting problems for homework due on Monday, a test on Tuesday, and covering polygons, regular polygons, similar and congruent figures, corresponding parts, and examples problems identifying shapes and comparing figure properties. 2. Example problems from the lesson ask students to identify polygons, determine if figures are similar or congruent, and specify corresponding parts of similar polygons. 3. Videos and pages from the textbook are referenced to provide additional information on the lesson topics.

Lesson 18 Warm­Up:
1) Find the unknown number: 1001 = 13
x
Which property is illustrated by the following equations:
2) 1/2 x 2/2 = 2/4
3) 1/2 x 2/1 = 1
4) Convert 3 16/7 to a mixed number.
5) Simplify: 2/5 x 2/5 x 2/5

Lesson 18:
*polygon ­ a closed, flat shape with straight sides
*regular polygon ­ a polygon with all sides equal and all angles equal
*Look at page 122!
*similar ­ figures that are the same shape, but not necessarily the same size
*congruent ­ figures that are the same shape AND the same size
*corresponding parts ­ sides or angles of similar polygons that occupy the same
relative positions
*Look at page 123!
