It could be a cylinder
A triangle has to have straight sides
This is called a heptagon.
A shape with straight sides is called a polygon. But it can have 3 or 4 sides as well.
A major sector of a curve.
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 two-dimensional shape with one curved side and four straight sides can be created, but there is not specific name for such a shape.
A quadrilateral is a shape with four straight sides. There are no curved sides in a quadrilateral.
no because a quadrilateral has straight sides if it were curved it wouldn't be a polygon because polygons must have straight sides
The shape you are referring to is called a "quadrilateral." A quadrilateral is a polygon with four sides and four vertices. It can have various combinations of straight and curved sides, including two straight sides and two curved sides. Examples of quadrilaterals with two straight and two curved sides include a kite or a concave quadrilateral.
There is no specific name for such a shape.
The shape that has one curved side and two straight sides is a semicircle. A semicircle is a two-dimensional shape that is half of a circle, with one curved side and two straight sides that connect at the endpoints of the curved side. The curved side of a semicircle is a semicircular arc, while the two straight sides are diameters that intersect at the center of the circle from which the semicircle is derived.

A triangle has to have straight sides
Plane polygonal shapes, that is, shapes with straight line boundaries must have 3 or more sides. If they have only two sides, these cannot be straight. They can wriggle all over the place and the shape has no name.
Circles have a completely curved shape, and NO sides. So do ovals.
The shape that has 1 curved side and 3 straight sides is a crescent. A crescent is a curved, closed shape that resembles a thin, partially illuminated moon. It is formed by the intersection of two circles or by removing a smaller circle from a larger one, resulting in one curved side and three straight sides.
