Math vocabulary

[BrerMom]

Can anybody help me with the mathematical names for these shapes?

1. An egg
2. A triangle-like shape with arcs instead of segments. The arcs are congruent.
3. A four-leaf clover.

TIA, the search engines have failed me.

I think number 1 would be an ellipse, but i have no clue about the others

Is this your triangle?

I believe they are:

1. Ovoid
2. Reuleaux Triangle
3. In general it is a Rose. Specifically with 4 pedals it is a Quadrifolium

Oh, you guys are GOOD! Yes, that's my triangle. Any help on how to pronounce it?

And an ovoid - yes! We were brain-storming this afternoon and thought it ended with oid but couldn't come up with the name.

Thank you, thank you!

Quadrifolium - Thanks, Bob!
