 Hello and welcome to the session. In this session we discussed the following question which says draw a cylinder and show its faces and edges. Does it have vertices? Let's move on to its solution now. First let's draw a cylinder. This is a cylinder. Now let's see the faces and the edges of the cylinder. So the flat surfaces of a solid are its faces. So let this be F1, this be F2. F1 is a flat surface or flat face. F2 is also the flat face of the cylinder. So cylinder has two flat faces and this is the curved face of the cylinder. Now let's mark its edges. The edges of a solid is the line segments of its skeleton. So this cylinder has two curved edges. This is one curved edge. Let this be C1 and this is the other curved edge C2. So we have drawn a cylinder and marked its edges and faces. As we say that a cylinder has two curved edges C1 and C2 as marked in the figure. Then a cylinder, one curved face, two flat faces which are F1 and F2. Now let's talk about the vertices. As you know that the corners of a solid shape are called its vertices. So in this figure of cylinder there are no corners. So we say that a cylinder has no vertex. So this completes this session. Hope you have understood the solution of this question.
