Yes, a shape can have three straight sides and one curved side. This type of shape is known as a triangle with one curved side, which is also called a curved triangle or a curved-sided triangle. The curved side can be a segment of a circle or any other curved shape, while the other three sides are straight lines.
A right circular cone could probably do that.

The center of the circle inscribed in a triangle is called the incenter. It is the point where the angle bisectors of the triangle intersect and is equidistant from all three sides of the triangle. The incenter is also the center of the circle that fits snugly within the triangle, touching each side at one point.
