Prerequisites
How to Solve Group by Fill Pattern Problems
Step 1: Examine each figure's interior fill pattern
Step 2: Identify which figures are solid (completely filled)
Step 3: Identify which figures are hollow (only outline, transparent interior)
Step 4: Identify any patterned fills (striped, dotted, crosshatch)
Step 5: Group figures with the same fill pattern together
Step 6: The classification basis is fill pattern type
Step 7: Answer how the figures are grouped
Example Problem
Example: Three solid shapes and three hollow shapes are shown. How are they grouped? Solution: Step 1: Group 1: Solid shapes (interior completely filled) Step 2: Group 2: Hollow shapes (only outline, transparent interior) Step 3: Classification basis = Fill pattern (solid vs hollow) Answer: Grouped by fill pattern - solid vs hollow
Pro Tips & Tricks
- Filled shapes have color inside the boundary
- Outlined shapes have only the border drawn (transparent inside)
- Striped patterns have parallel lines inside
- Dotted patterns have dots arranged regularly
- Crosshatch patterns have intersecting lines
- The fill color itself doesn't matter - only presence/type of fill
