Cut Shape Prediction
Cut Shape Prediction problems present a folded paper with a cut made along some edge or shape. You must determine the shape of the cutout or the pattern of openings when the paper is unfolded. These problems test your understanding of how cut shapes reflect across fold lines.

Prerequisites
How to Solve Cut Shape Prediction Problems
Step 1: Identify the fold lines and the type of fold (vertical, horizontal, diagonal)
Step 2: Note the shape and location of the cut on the folded paper
Step 3: The cut goes through all layers of the folded paper
Step 4: Reflect the cut shape across each fold line to create the complete pattern
Step 5: For multiple folds, reflect sequentially
Step 6: The final unfolded shape is the combination of the original cut and all its reflections
Step 7: Visualize or draw the complete symmetrical pattern
Example Problem
Example: A paper folded in half horizontally has a semicircle cut from the folded edge. What shape appears when unfolded? Solution: Step 1: Fold line is horizontal at the center Step 2: Semicircle cut is on the folded edge Step 3: The cut goes through both layers Step 4: When unfolded, the semicircle reflects across the fold line Step 5: Two semicircles facing each other form a full circle Answer: A full circle
Pro Tips & Tricks
- A cut on the folded edge creates a symmetrical shape when unfolded
- A triangle cut from the folded edge creates a diamond or kite shape
- A semicircle cut from the folded edge creates a full circle
- A rectangular cut from the folded edge creates a larger rectangle
- Cuts not on the fold line create multiple separate cutouts
- The number of cutout pieces = 2^(number of folds)
