 Hello and welcome to the session. In this session we discuss the following question which says identify the figure and name its faces, vertices and edges. Before proceeding with the solution let's recall the definition for faces, vertices and edges. First we have faces. Each flat part of a solid is called its face. Next is the definition for vertices. Each corner where three faces of solid meet is called its vertex and the plural of vertex. Then we have the definition for edges, the two faces of solid. The key idea to be used for this question. Now let's proceed with the solution. This is the given figure. The given figure is a triangular prism. It is made up of two parallel n faces each one of which is a triangle and three lateral faces each one of which is a rectangle. Now we shall name the faces, vertices and edges of this triangular prism. Now first let's name the faces. It has two triangular faces that is A, B, C and D, E, F are the two triangular faces of this triangular prism. Then it has three rectangular faces which are named as A, B, E, D. Then A, D, F, C, C, B, E, F. Next let's name the vertices of this triangular prism. It has in all six vertices which are A, B, C, D and F. Then we have the edges of the triangular prism. We know that edge is a line where two faces of a solid meet. So for this triangular prism we have nine edges which are A, B, B, C, C, A, D, E, F, D, A, D, B, E and C, F. So for this triangular prism we have named its faces, vertices and edges. This completes the session. Hope you have understood the solution for this question.
