Question

The number of diagonals that can be drawn from one vertex in a 7-sided polygon is ____.

• A. 4
• B. 5
• C. 6
• D. 7

Answer 1

The correct option is A 4

The diagonal is a segment that connects two non-consecutive vertices in a polygon.
The number of diagonals that can be drawn from any vertex in polygon is three less than the number of sides.
Let n be the number of sides in a polygon, so the number of diagonals that can be drawn from one vertex is (n-3)
So, number of diagonals that can be drawn from one vertex of a 7-sided polygon is 4.
