Geometry & Space — Understanding Shape, Dimension, and Structure

Geometry connects mathematics directly to the physical universe. 
It studies shapes, distances, transformations, and the nature of dimension.

Topics ideal for this forum:
• Euclidean geometry 
• Lines, angles, triangles, circles 
• Coordinate geometry 
• Vectors & directions 
• Symmetry & transformations 
• 3D geometry 
• Higher dimensions 
• Curved surfaces & basic topology 

From simple constructions to the geometry of spacetime — it all belongs here.
