# Do we need tags for 'rectangle', 'circle', 'triangle', 'hexagon' and 'shape'?

It came to my attention that there is a tag for

• , no description, 76 questions
• , with description, but no usage guideline, 52 questions
• , with description, but no usage guideline, 78 question
• , with description, but no usage guideline, 50 questions
• , with description, but no usage guideline, 115 questions
• , with description, but no usage guidelines, 51 question**

which all relate to more or less the same type of thing.

A question that comes to mind is, can someone be an expert in rectangle, circle, shape?

• Do we need all of these tags?
• Could/should we merge them all to the single shape or polygon?
• Could/should we merge some of them?
• Should we simply remove them all?
• Are these tags only accessory to other more valuable tags?

** The shape could be relevant to 2d and 3d objects, while all of the others are only relevant to 2d (planes).

The few cases where I can think, offhand, that these tags might even potentially apply (rasterization, collision detection and response, and so on) have better, more appropriate tags available already... or we should make appropriate tags (for example, circle-circle collision detection might be useful, but I don't think circle alone is).
• But then we'd also need the tags rectangle-rectangle, circle-rectangle, triangle-circle, circle-line, etc, wouldn't we? – Alexandre Vaillancourt Jan 5 '17 at 16:32
