Group by Line Type
Group by Line Type problems involve classifying figures based on whether their boundaries are curved, straight, or a mix of both. Circles have curved edges, polygons have straight edges, and shapes like hearts or stars may have mixed edges. These problems test understanding of geometric edge properties.

Introduction to Group by Line Type
Group by Line Type problems involve classifying figures based on whether their boundaries are curved, straight, or a mix of both. Circles have curved edges, polygons have straight edges, and shapes like hearts or stars may have mixed edges. These problems test understanding of geometric edge properties.
Prerequisites
How to Solve Group by Line Type Problems
Step 1: Examine the boundary of each figure
Step 2: Determine if the figure has only curved edges (circle, ellipse)
Step 3: Determine if the figure has only straight edges (polygon)
Step 4: Determine if the figure has a mix of curved and straight edges
Step 5: Group figures with the same line type together
Step 6: The classification basis is line type (curved vs straight vs mixed)
Example Problem
Example: Three circles (curved), three squares (straight). How are they grouped? Solution: Step 1: Circles have only curved edges Step 2: Squares have only straight edges Step 3: Group 1: Curved edge shapes (circles) Step 4: Group 2: Straight edge shapes (squares) Step 5: Classification basis = Line type Answer: Grouped by line type - curved edges vs straight edges
Pro Tips & Tricks
- Circle, ellipse, oval = curved edges only
- Polygons (triangle, square, pentagon, hexagon) = straight edges only
- Heart shape = mixed edges (curved top, straight/curved bottom)
- Star shape = mixed edges (straight lines but intersecting)
- Semi-circle = mixed edges (curved top, straight base)
- All sides of a polygon are straight line segments
