There is no specific name for such a shape.
Yes
A shape with three linear sides and one curved side can be drawn, but such a shape has no specific name.
OK, SO a shape with fewer than four straight sides is a triangle, which has three (3) straight sides. Hope this helps! LOOPDOP says: A circle is a shape. And it has no straight sides..... isn't that "fewer"?
2-dimensional shapes, with three straight sides have three vertices.
A triangle. An equalateral triangle

Triangles have three straight sides.
The answer is: MAMA DAT SO HARD COME HELP MOOMY! I KNOW IT A CIRCLE

This is a description of a scalene triangle.

A closed shape with three or more straight sides is called a polygon. Examples of polygons include triangles, squares, pentagons, hexagons, and so on.
There are no polygons (shapes with only straight-line sides) with fewer than three sides, but if you allow shapes with curved sides there are many possibilities. Examples include semicircles, annuli (donut shaped), and crescents.From Caromal, and Izzyk9God just say a CONE!!!
Because that is how a polyhedron is defined.
