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: 3 sides (triangle)
- Figure 2: 2 sides (2-gon)
- Figure 3: 1 sides (1-gon)
- Figure 4: 0 sides (0-gon)
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 loses one side in sequential transformation
VERIFICATION:
Consistent transformation: -1 side per step ✓
APPLICATION:
Figure 5: 0 - 1 = -1 sides
Shape: -1-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
