🎯 WALT: We Are Learning To calculate angles in polygons

Success Criteria:

• I can identify interior and exterior angles

• I can calculate missing angles using polygon formulae

• I can apply angle properties to solve problems

Key Formulae:

• Sum of interior angles = (n - 2) × 180°

• Each interior angle in regular polygon = (n - 2) × 180° ÷ n

• Sum of exterior angles = 360°

📚 Part 1: Multiple Choice Questions

✏️ Part 2: Calculations and Problem Solving

Formula: Sum = (n - 2) × 180°

Answer: ____________°

Step 1: Find sum of all interior angles: ____________°

Step 2: Divide by number of angles: ____________°

Remember: Sum of interior angles in quadrilateral = 360°

x = ____________°

Hint: Sum of exterior angles = 360°

Number of sides = ____________

🌟 Extension Activities

For Advanced Learners:
