### Identifying Similar Triangles

by Patricia Finck

8.G.5 Students use facts about the angle sum and exterior angles of triangles to calculate missing angles. Students apply angle theorems to parallel lines cut by a transversal. Students interpret geometrical diagrams using mathematical properties to identify similarity of triangles. © 2012 MARS, Shell Center, University of Nottingham

### The Pythagorean Theorem: Square Areas

by Patricia Finck

8.G.7 Students use the area of right triangles to deduce the areas of other shapes. Use dissection methods for finding areas. Students organize an investigation systematically and collect data. Students deduce a generalizable method for finding lengths and areas (The Pythagorean Theorem.) © 2012 MARS, Shell Center, University of Nottingham
