Question

In figure, name the three edges which meet in the vertex G.

Answer 1

Hint: In this question we have to find the names of the edges, which meet the vertex G. Look at the figure carefully and recall the definition of edge and vertex.Here given figure is a three dimensional body , having faces, edges & vertices . In geometry, a three dimensional figure can be defined as a solid figure or an object or shape that has three dimensions – length, breadth & height. Unlike two dimensional figures, three dimensional figures have thickness or depth. In this figure , we can see that there are 8 vertices ( A, B,C,D ,E ,F,G,H ) , 12 edges ( AB, BC, CD,AD,EF,FG,GH,EH,AE,HD,BF,CG)&6 faces (ABCD,EFGH,AEHD,BCGF,AEFB &CDHG) .

Complete step by step answer:
We know that, when two or three (basically three in 3-Dimensional figures) edges meet at a point, that point is called vertex.
At G, three edges meet and they are GH (with breadth ‘b’), GF (with height h) and CG (with length l).
Therefore, the three edges that meet vertex G of a cuboid are GH, GF & CG.

Note:
Most important step is to relate the asked question with the given diagram & that will ultimately help you get the correct answer.
 For any three - dimensional solid figures: -
-The surface of solid is called face.
-Edges are formed when two faces meet.
-Vertices are formed when three edges are met.
