Build and study complex patterns using the language of transformations Students can use properties of angle sums to reason about how figures will fit together and can repeatedly use rigid transformations to make interesting repeating patterns of figures. Print the Deducing Angle Measures blackline master. If possible, make these copies on cardstock so that students will have an easier time tracing shapes after they cut them out.
