Departmental Workshops - Angle Properties

These workshops are written to provide your mathematics team with structured professional development you can deliver in-house utilizing all members' expertise and knowledge. We believe 3 – 6 modules per year could be an ideal balance.

This module explores the language and notation associated with angle properties and reasoning and further highlights the importance of giving context to geometry. The first activity proposes a circle task to help students to understand the concepts. As the activities progress, the glossary of angle properties term expands.This workshop explores:

  • the importance of giving a context to geometry, in this case the use of parallel lines and triangles in bridge design;
  • the significance of being able to see equalities between angles before becoming too concerned about the formal language that fits the description;
  • familiarity with formal language;
  • the use of a practical “demonstration”, with associated reasoning, that establishes that the angles in a triangle sum to 180° as a preliminary to using a card sort as a formal proof
