Group by Number of Sides
Group by Number of Sides problems involve classifying polygons based on how many sides they have. Common categories include triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), and circles (0 sides). These problems test your understanding of polygon properties and side counting.

Introduction to Group by Number of Sides
Group by Number of Sides problems involve classifying polygons based on how many sides they have. Common categories include triangles (3 sides), quadrilaterals (4 sides), pentagons (5 sides), hexagons (6 sides), and circles (0 sides). These problems test your understanding of polygon properties and side counting.
Prerequisites
How to Solve Group by Number of Sides Problems
Step 1: Count the number of sides for each figure
Step 2: Circles have 0 sides (or infinite, but treated as curved)
Step 3: Triangles have 3 sides
Step 4: Quadrilaterals have 4 sides (squares, rectangles, rhombuses, etc.)
Step 5: Pentagon = 5 sides, Hexagon = 6 sides
Step 6: Group figures with the same side count together
Step 7: The classification basis is number of sides
Example Problem
Example: Figures: two triangles, two squares, two pentagons. How are they grouped? Solution: Step 1: Triangles have 3 sides Step 2: Squares have 4 sides Step 3: Pentagons have 5 sides Step 4: Group 1: 3-sided shapes (triangles) Step 5: Group 2: 4-sided shapes (squares) Step 6: Group 3: 5-sided shapes (pentagons) Step 7: Classification basis = Number of sides Answer: Grouped by number of sides
Pro Tips & Tricks
- Triangle = 3 sides, Quadrilateral = 4 sides
- Pentagon = 5 sides, Hexagon = 6 sides
- Heptagon = 7 sides, Octagon = 8 sides
- Circle = 0 straight sides (curved shape)
- Square, rectangle, rhombus all have 4 sides
- Count each side carefully - don't confuse vertices with sides
