Congruent+Figures

=Congruent and Similar Figures=

-
 * Exploration activity for congruent and similar figures. I printed out the Congruent figures paper with triangle BCD for half the class, and the one with ZYX for the other half. I had them measure the angles and sides of the triangle. We then made a chart to determine the corresponding sides and angles and write "definitions" for corresponding sides and angles of congruent figures. Then I used the back as practice (most of the problems are from older FCPS resources).
 * The second part of the activity is for similar figures. I had students answer the 4 questions independently and then discuss with a group to determine that corresponding angles were congruent and corresponding sides were in proportion. They do not use proportions to determine a missing value...just identify corresponding sides in grade 7...
