Its+all+the+Same

8th Grade: Geometry Overview:
 * Section A**: Students investigate similar shapes uysing a tesselation model (using small congruent shapes to form larger similar shapes). Students investigate properties of parallel lines within their tesselations.
 * Section B**: Students use additional methods (enlargement factor and ratio tables) to determine corresponding lengths of similar triangles.
 * Section C**: This section focuses on the formalization of Section A and B through the creation of similar shapes and methods to prove or justify similarity.
 * Section D**: This section connects the prior sections as the students solve real-world problems using the concept of similarity.
 * Section E**: This section extends the students exploration into examining similar shapes on a corrdinate plane. Connections are made to earlier 7th and 8th grade units as students use the Pythagoream Theorem and the concept of slope to determine distances in a coordinate plane and examine properties of perpendiclar lines in the coordinate plane.
