Question

how many diagnals does a regular hexagon have with formula​

Answer 1

Answer:

A regular hexagon have 3 diagonal

Answer 2

Answer:

9

Step-by-step explanation:

The number of diagonals in a polygon is given by $\frac{n(n-3)}{2}$ where n is the number of sides of the polygon.

This can be explained as-

• there are n vertices in a polygon.
• there are n-3 diagonals from a vertex. The 3 points being excluded here are the point's 2 neighbours and the point itself.
• Each diagonal has 2 ends⇒The diagonals will be counted twice, therefore we divide it by 2.

Hope this answers your question.
