Geometry and Angles · Semester 2

Angles on a Straight Line and at a Point

Students will identify and apply properties of angles on a straight line (sum to 180°) and angles at a point (sum to 360°).

Key Questions

  1. Explain why angles on a straight line add up to 180 degrees.
  2. How can you use the properties of angles at a point to find unknown angles?
  3. Analyze real-world examples where these angle properties are observed.
