A polygon is a 2 dimensional shape made up of straight line segments which are connected with each other, thus giving it a closed shape. A circle, square, rectangle, and triangle are some examples of two-dimensional shapes and these shapes can be drawn on paper.

In geometry, a closed shape can be defined as a enclosed shape or figure whose line segments and/or curves are connected or meet. They start and end at the same point.
For example circle.

A polyhedron is regular if its faces are congruent regular polygons and the same number of faces meet at each vertex. For example, a cube is a platonic solid because all six of its faces are congruent squares. There are five such solids– tetrahedron, cube, octahedron, dodecahedron and icosahedron.

Sudhir Mehta answered |
The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments and lines that result in two straight "sides" meeting at one place.

Explanation:
A solid figure formed by two congruent parallel circles joined by a curved surface is called a cylinder.
Cylinder:
A cylinder is a three-dimensional geometric shape that consists of two congruent parallel circular bases connected by a curved surface. The curved surface is formed by connecting all the points on the circumference of the two bases with vertical lines. The two bases are parallel and congruent, meaning they have the same size and shape.
Properties of a Cylinder:
- Bases: A cylinder has two circular bases that are parallel and congruent to each other. The bases are the top and bottom faces of the cylinder.
- Height: The height of a cylinder is the perpendicular distance between the two bases. It is also the length of the vertical line connecting the centers of the two bases.
- Radius: The radius of a cylinder is the distance from the center of one of the bases to its circumference. Since the bases are congruent, they have the same radius.
- Curved Surface: The curved surface of a cylinder connects all the points on the circumferences of the two bases. It is formed by vertical lines that are perpendicular to the bases.
Example:
Consider a can of soda as an example of a cylinder. The top and bottom of the can are circular and have the same size and shape. These circular bases are connected by the curved surface of the can. The height of the can is the distance between the top and bottom, and the radius is the distance from the center of the circular bases to their circumferences.
In conclusion, a solid figure formed by two congruent parallel circles joined by a curved surface is called a cylinder. It is a three-dimensional shape with two circular bases and a curved surface connecting them.

Both a cylinder and a sphere will roll since they both contain a curved face. Spheres will roll in every direction, however, the cylinder will only roll in one direction when placed on its side.

A circle is a plane closed figure enclosed by a curve, having no sides and no corner (vertex). Every point in the curve is situated at equal distance from a definite point within the closed figure.

A cone is a three-dimensional solid that has a circular base joined to a single point (called the vertex) by a curved side. You could also think of a cone as a “circular pyramid”.

An edge is the line segment where two faces meet. You can see by looking at this cube that the faces intersect in a line. Many solid figures have more than one edge. A vertex is a point where several planes meet in a point.
