About Geometry Worksheet Assignment 6.7:     

 

Assignment 6.7 is a development of the relationships of lengths of sides and angle measures in the image and preimage of a dilation of polygons.

 

Prerequisite Skills:  Name and identify dilations of polygons (Assignment 6.6).  Measure sides and angles of polygons (Assignment 3.2).  

Solve proportions (Assignment 6.2).

 

Theorem:  In a dilation of polygons: the lengths of the coreesponding sides are proportional; the corresponding angles are congruent.
