Front

Hexaflexagon

Back

A folded shape made from triangles that has multiple sides you can flip and fold.

Front

Möbius Strip

Back

A shape that has only one side and one edge, created by twisting a strip of paper and joining the ends.

Front

Reuleaux Triangle

Back

A shape that looks like a triangle but has rounded corners, maintaining the same width everywhere.

Front

Twisted Cylinder

Back

A shape made by twisting a strip of paper twice before joining the ends, making it hard to distinguish the inside from the outside.

Front

Fixed-width shapes

Back

Shapes that maintain the same width regardless of orientation, useful in geometry and engineering.

Front

Properties of Hexaflexagons

Back

They can be folded and flipped to reveal different faces, demonstrating geometric flexibility.

Front

Applications of Möbius Strips

Back

Used in various fields such as mathematics, art, and engineering to illustrate concepts of non-orientability.

Front

Real-world examples of Reuleaux Triangles

Back

Used in drill bits and other tools where a constant width is required.

Front

Characteristics of Twisted Cylinders

Back

They challenge traditional notions of inside and outside in geometry.

Front

Importance of Fixed-width shapes in design

Back

They optimize space and material usage in engineering and architecture.
