Welcome to our brand new tutorials for Geometry. Each tutorial will take you through a construction/theorem from the Geometry Course of Study at Junior or Leaving Certificate.The tutorials will explore both conceptual and procedural knowledge for teaching and learning . Each video concludes with a list of additional resources available on the website for use in the classroom.
