Occlusion Hiding
Occlusion Hiding problems hide a simple shape (circle, square, triangle) behind other, larger shapes. The hidden shape is partially visible, peeking out from behind the foreground objects. You must identify the shape based on the visible parts and the context of the overlapping figures.

Introduction to Occlusion Hiding
Occlusion Hiding problems hide a simple shape (circle, square, triangle) behind other, larger shapes. The hidden shape is partially visible, peeking out from behind the foreground objects. You must identify the shape based on the visible parts and the context of the overlapping figures.
Prerequisites
How to Solve Occlusion Hiding Problems
Step 1: Identify the foreground shapes that are causing the occlusion.
Step 2: Look for parts of a shape that are not covered by the foreground.
Step 3: Mentally complete the hidden shape by extrapolating from the visible parts.
Step 4: The visible parts might include a curved edge (suggesting a circle), a straight edge (suggesting a polygon), or a corner.
Step 5: Consider the context: the hidden shape is often placed so that it is partially visible from multiple sides.
Step 6: Once you have a candidate shape, verify that it fits perfectly behind the foreground objects.
Step 7: Select the answer option that matches the occluded shape.
Example Problem
Example: A large square partially covers a shape. The visible parts show a curved edge. The hidden shape is likely a circle. Solution: Step 1: Foreground shape: square. Step 2: Visible part: a curved line. Step 3: A curved line suggests a circle or an oval. Step 4: A circle is the most common hidden shape in such puzzles. Step 5: Mentally place a circle behind the square; the visible part matches. Answer: Circle
Pro Tips & Tricks
- A curved visible edge strongly suggests a circle or an oval.
- Two straight edges meeting at a corner suggest a square or rectangle.
- Three straight edges suggest a triangle.
- The hidden shape is usually centered behind the foreground objects.
- The visible parts are often at the edges of the foreground shapes.
- If multiple parts are visible, connect them mentally to form the whole.
