Question 1
Identify the geometric transformation rule:
Figure 1:
Figure 2:
Figure 3:
Figure 4:
What shape comes next?
PATTERN ANALYSIS:
Step 1: Identify each shape by counting sides
- Figure 1: 5 sides (pentagon)
- Figure 2: 6 sides (hexagon)
- Figure 3: 7 sides (heptagon)
- Figure 4: 8 sides (octagon)
Step 2: Analyze side count progression
- Fig 2 - Fig 1 = 1 sides
- Fig 3 - Fig 2 = 1 sides
- Fig 4 - Fig 3 = 1 sides
RULE HYPOTHESIS:
Each polygon gains one side in sequential transformation
VERIFICATION:
Consistent transformation: +1 side per step ✓
APPLICATION:
Figure 5: 8 + 1 = 9 sides
Shape: 9-gon
GEOMETRIC PRINCIPLES:
- Regular polygons maintain equal side lengths
- Interior angle changes with side count
- Formula: Interior angle = (n-2) × 180° / n
COMMON MISTAKES TO AVOID:
- Miscounting sides in complex polygons
- Confusing vertices with sides
- Not recognizing regular vs irregular polygons
- Missing the consistent arithmetic progression
