Question 1
Figure Analogy: A : B :: C : ?
Figure A undergoes two transformations to become B: rotated 90° anticlockwise AND enlarged by 1.5x. Apply both to C.
Step-by-Step Solution:
STEP 1: Identify First Transformation (Rotation)
- Figure A orientation: Triangle pointing right
- Figure B orientation: Triangle pointing upward
- First transformation: 90° anticlockwise rotation
STEP 2: Identify Second Transformation (Scaling)
- Measure A dimensions: Small triangle (base ≈ 20 units)
- Measure B dimensions: Larger triangle (base ≈ 30 units)
- Second transformation: 1.5× scaling (enlargement by 50%)
STEP 3: Determine Transformation Sequence
- Method 1: Rotate first, then scale
- Method 2: Scale first, then rotate
- Result: Same final figure (transformations commute)
- Standard approach: Rotate, then scale
STEP 4: Apply Rotation to C (90° anticlockwise)
- Original C: Vertical rectangle (height > width)
- After rotation: Horizontal rectangle (width > height)
- Internal dot: Rotates with figure to new position
STEP 5: Apply Scaling to Rotated C (1.5×)
- Current dimensions: Already rotated rectangle
- Apply 1.5× to both length and width
- Internal dot: Maintains relative position, scales proportionally
STEP 6: Verify Combined Transformation
- Original: Vertical rectangle, small size, dot at top
- After rotation: Horizontal rectangle, small size, dot on left
- After scaling: Horizontal rectangle, 1.5× larger, dot on left (scaled position)
Answer: Rectangle in horizontal orientation (rotated 90° anticlockwise), dimensions increased by 1.5×, with dot repositioned according to both transformations
