Question

the given figure has ____________ edges and _____________ vertices.

• A. $12,8$
• B. $14,8$
• C. $9,7$
• D. $15,10$

Answer 1

The correct option is D $15,10$

A vertices is a corner where $2$ lines meet and an edge is a line segment which connects $2$ vertices.

For better understanding, consider it to be a hut as shown in figure and count edges and vertices.

Now it has $10$ vertices where two or more edges meet and $15$ edges.
