What is a triangle with one curved side called?

Answer 1

Oh honey, that's not a triangle, that's a whole other shape called a "curvilinear triangle." It's like a regular triangle, but with a sassy curve thrown in there for some flair. So, technically speaking, it's not a triangle at all, but nice try though!

Answer 2

Oh, dude, that's like a circle. You know, that round thing with no corners? Yeah, that's the one. So, technically, a triangle with one curved side would just be a circle. But like, who's out here making curvy triangles anyway?

Answer 3

A triangle with one curved side is called a curvilinear triangle. This type of triangle has one side that is not straight, but instead follows a curved path. Curvilinear triangles are not as common or well-known as traditional triangles with straight sides, but they still adhere to the fundamental properties of triangles, such as having three sides and three angles that add up to 180 degrees.
