Math, possibly geometry?, question. [View all]

I am using a shape with my students that looks like a parallelogram, but the left and right sides are curved instead of straight. The curves are "parallel" to each other.

I don't know how else to describe it... It kind of looks like a very thick letter C, but with a flat top and bottom. Does this shape have a name?

Thanks very much!

Not one of the more common shapes, but like all symetrical shapes it does indeed have a name. Captain Stern Jan 2014 #3

Thanks, but the curves are wrong. femmocrat Jan 2014 #8

Sounds like a lens, maybe this negative meniscus ? jakeXT Jan 2014 #9

"lens-shaped" might be a good generic term that covers all of those struggle4progress Jan 2014 #10

Are the curves segments of concentric circles? pokerfan Jan 2014 #12

That is almost it. Thank you very much. femmocrat Jan 2014 #15

Looks like it's called a "sector of an annulus" pokerfan Feb 2014 #22

I was great at working proofs in geometry back in grade 11. Don't remember much applegrove Jan 2014 #13
