Question 1

Find the odd figure out based on edge properties. Figure A: Figure B: Figure C: Figure D: Figure E:
Step-by-step Solution:

Step 1: Analyze edge types in all figures
- Examine whether edges are curved or straight
- Check each boundary of every figure

Step 2: Identify the common edge property
- Four figures have CURVED edges
- Circles, ellipses, and curved shapes share this property
- Curved boundaries define this group

Step 3: Find the figure with different edges
- Figure B has only STRAIGHT edges
- All boundaries are linear segments, not curves
- This is a polygon (square) versus curvilinear shapes

Step 4: Verification
- Trace the boundary of each figure
- Four figures: Curved boundaries
- One figure (Figure B): Straight boundaries only

Edge Analysis Strategy:
- Run your finger/eye along each edge
- Determine if it's a straight line or curved arc
- Classify each figure by its edge type

Geometric Distinction:
- Polygons: Straight edges only (squares, triangles, pentagons)
- Curvilinear figures: At least one curved edge (circles, ellipses)

Common Mistake: Not examining all edges carefully, especially in complex shapes.
