Introduction to Fill Property Classification
Fill Property Classification problems involve grouping figures based on whether they are filled (solid color inside) or outlined (only border, transparent interior). These problems test your ability to recognize fill patterns and distinguish between solid and hollow shapes.
Prerequisites
How to Solve Fill Property Classification Problems
Step 1: Examine each figure to see if it has interior fill color
Step 2: Note which figures are completely filled (solid interior)
Step 3: Note which figures have only outline (hollow/transparent interior)
Step 4: Count the number in each group (usually equal in classification problems)
Step 5: The classification basis is the presence or absence of interior fill
Step 6: Verify that all figures in each group share the same fill property
Step 7: Select the option that describes this distinction
Example Problem
Example: Three shapes have solid color fill, three have only outlines. How are they classified? Solution: Step 1: Group 1: Shapes with solid interior color Step 2: Group 2: Shapes with hollow interior (only outline) Step 3: Classification basis = Filled vs Outlined shapes Answer: Filled shapes vs Outlined shapes
Pro Tips & Tricks
- Filled shapes have color inside the boundary
- Outlined shapes have only the border drawn (transparent inside)
- Partially filled shapes (like stripes) belong to a different classification
- Cross-hatching or patterns are also considered fill types
- The fill color itself doesn't matter - only presence vs absence
- Some problems may use solid vs patterned fill
