Objective: Explain properties of triangle for different types of triangle
Subtopics to be covered:
- Revise types of triangles based on sides and angles
- Property on sum of lengths of sides of triangle
- Exterior angle of triangle and its property
Learning Outcome:
- Students can identify type of a triangle based on the measurements given
- They can tell based on given side measures, a triangle can be drawn or not
