 Hello and welcome to the session. In this session we discussed the following question which says, draw a square pyramid and name its faces, vertices and edges. Firstly, recall the definition for faces, vertices and edges. We know that each flat part of a solid is called, then next we have vertices. Each corner where three faces of a solid meet its vertex and the plural of vertex is vertices. Then the next definition is for edges. The two faces of a solid meet in a line called an edge. This is the key idea to be used in this question. Now let's move on to the solution. First we need to draw a square pyramid. This figure O A B C D is a square pyramid, its base is a square and its side faces are triangles which have a common vertex. Now let's name the faces of the square pyramid O A B C D. We know that each flat part of a solid is called its base. So it has total five faces, these five faces, one is a square face which is A B C D and four are triangular faces which are O A D O C D O B C and O A B. Next let's name the vertices of the square pyramid O A B C D. The corner where three faces of a solid meet is called its vertex. So for the square pyramid O A B C D we have five vertices which are O A B C and D. Then next name the edges of the square pyramid. It has eight edges. Now the edges are the line where two faces of a solid meet. So for this square pyramid O A B C D we have eight edges which are A B B C C B D A O A O B O C and O D. So we have named the faces, vertices and edges of the square pyramid. So this completes the session. Hope you have understood the solutions for this question.
