During this unit of work, students will:

1. revisit and apply their knowledge & understanding of geometric properties, measurement, angle relationships and deductive reasoning
2. identify and use new circle features and terminology related to angles in circles (e.g. secant, subtend, angle standing on an arc or chord)
3. explore circle properties through various modes, including compass-and-straight-edge construction and dynamic geometry software, as well as suggest possible conjectures and apply deductive reasoning to prove and solve problems (unknown sides and angles) related to:
   • Chord Properties
   • Angle Properties
   • Tangent & Secant Properties

Key Goal: develop students' deductive reasoning and problem-solving skills in the context of presenting proofs of circle geometry properties and solving related problems
