Teach IB Maths MYP Year 1 Unit 1.4.4 with a complete slide deck covering angles in triangles.

Students learn how to:
• Use the fact that angles in a triangle total 180°
• Find missing interior angles in triangles
• Use equal-side markings in isosceles triangles to identify equal angles
• Apply the exterior-angle fact
• Write equations to solve triangle-angle problems
• Use labelled diagrams as evidence for angle relationships
• Check solutions by confirming that interior angles total 180°
• Identify and correct common triangle-angle errors
• Apply triangle-angle facts to roof trusses, bridges, frames, and other real-world structures
• Explain geometric reasoning clearly using diagrams, equations, and angle facts
