Question

In a pentagon how many diagonals can be drawn from a vertex to other vertices ​

Answer 1

1. when counting the diagonals to count each one only once.
2. For example, a pentagon ($5$ sides) has only $5$ diagonals.
3. Each vertex has two diagonals, so if you counted each diagonal from every vertex twice, you might think there were $10$ diagonals.

Answer 2

Answer:

In a pentagon, 10 diagonals can be drawn from a vertex to other vertices.

Step-by-step explanation:

Since pentagon has five vertices with five diagonals.

But from each vertex, two possible diagonals can be drawn. Thus, each vertex has two diagonals.

Total number of diagonals = Number of vertices × Possible number of diagonals from each vertex.

Total number of diagonals = 5 × 2

                                            = 10

Therefore, 10 diagonals can be drawn from a vertex to other vertices in a pentagon.
