It could be a stretched circle - a bit like an ellipse except that an ellipse does not have straight lines.
A cylinder seems to fit the description
A polygon is any closed 2-D shape which bounded by straight lines.
a regular square!
A major sector of a curve.
It is a closed 2-dimensional shape, bounded by seven straight lines.
A shape with 4 straight lines in which there are 2 parallel and 2 unparallel lines is called a Trapezium.
A quadrilateral is a shape with four straight sides. There are no curved sides in a quadrilateral.
It could be a sector although that implies that (a) the curved side is part of a circle which it need not be and (b) that the two straight lines meet at the centre of the circle - again an assumption not justified by the requirements of the question.
1 straight line. An infinite number of curved lines.
There are two classification A. Straight lines 1.Horizontal lines - these are straight lines in lying position and they suggest calmness. 2. Vertical lines - these are straight lines in upward position and they suggest height and power. 3. Zigzag lines - these are straight lines, too. They suggest disorderliness and trouble. 4. Slanting lines - these are straight lines that give the feeling of action or motion. B.Curved Lines - lines that suggest meanings like motion and feelings. 1. Wavy lines - these lines suggest gracefulness or continuity. 2. Spiral - these are curved lines that suggest action and motion. 3. Concave - a line curved inward. 4. Convex - a line curved outward.
In 2 dimensions, a polygon. In 3 dimensions, a polyhedron.
It is a closed 2-dimensional shape bounded by six straight lines.
It is simply an elongated circle, possibly an oval but NOT an ellipse. It is not an ellipse because it has two straight sections. An ellipse is curved at all points along its perimeter.

a polygon is a shape with 5 corners A pentagon has five sides. A polygon has 3 or more sides, is closed and has line segments as the sides ( no curved sides ).
