How many diagonals can be drawn from one vertex of a 12 sided polygon.
****WORK NEEDED TO BE SHOWN****
Draw any convex polygon of n sides.
From any vertex, there are n-1 other vertices to reach. But two of those are adjacent, so a joining line is just a side.
That leaves n-3 other vertices. Joining to them will form diagonals.
HOW many diagonals are in ONE vertex on A 12 SIDED Polygon
this is 7th grade pre algebra!!
****WORK NEEDED****
To find the number of diagonals that can be drawn from one vertex of a 12-sided polygon, we can use a formula.
The formula for finding the number of diagonals in a polygon with n sides is n(n-3)/2.
In this case, the polygon has 12 sides, so we substitute n = 12 into the formula:
Number of diagonals = 12(12-3)/2
= 12(9)/2
= 108/2
= 54
Therefore, there are 54 diagonals that can be drawn from one vertex of a 12-sided polygon.
