A line? What do you mean only two sides? – terdon Sep 24 '13 at 17:57
Yes in a 2D space it would be a line. I guess I was trying to speak of an L shaped object in 3D space, which doesn't actually have 2 sides. bbc.co.uk/schools/gcsebitesize/design/images/… Is there a term more specific than 'L' shaped, or polygon? – Tom Swifty Sep 24 '13 at 18:03
Sorry, I still don't get your definition. How is that different from an F or Y or T shape? Perhaps you could use angle? Give us some more shapes that match the definition and some that come close but don't. – terdon Sep 24 '13 at 18:08
Often called a "wedge". – Greg Hullender Sep 24 '13 at 18:22
Thanks @GregHullender !! – Tom Swifty Sep 24 '13 at 18:24

In 2-D, if the line does not enclose a space (e.g., a hexagon) then a figure with two connected straight lines can be termed "perpendicular line segments" or a "vertex." Vertex is more general, p.l.s. means the two lines are at 90 degrees to one another.

But a bracket is a solid object, a drawing of a bracket could be in 2-D or 3-D. If your 2-D, L-shaped object were drawn showing the width of the two segments then the general term would be a polygon. Imagine a cross with the top part lopped off, the two parts each has a width and a length.

I think what you call it would depend on the context.

I'd just call it an 'EL' in general.

But if you're looking at any angle and not just a right-angled L, I think you could call it an open-triangle although you wouldn't call it a single word.

The context is writing a math word problem about "EL" shaped brackets. Are you recommending EL-shaped or L-shaped? – Tom Swifty Sep 24 '13 at 18:11
@TomSwifty I meant to use the letter "L" but wrote the pronunciation in capital letters. Thanks for that reminder. – itsols Sep 24 '13 at 18:15
