## Teaching Geometry with Transformations and Geogebra

Transformations play the key role in determining congruency and similarity of figures and in this course you will see how to use Geogebra to explore geometry through this lens. Using a “transformations first” approach unifies many ideas in Euclidean Geometry and helps to tie together the coordinate and synthetic treatment of geometric topics. This fundamental shift in emphasis is a central tenant of the Common Core Curriculum in Geometry. Come and look at ideas from a new perspective — re-immerse yourself in geometry like you were a student — find new ways to teach topics — make symmetry have a […]
