Take central point inside the polygon, draw lines to vertices of polygon from that point. Total angle at that point when all angles with respect to that point to vertices are added is 360°.
So, angle at centre is 360/(No of sides)
Since Centre Point makes Isosceles triangle with each side, (180-360/N) will give angle between two sides of the polygon.

Remember the name Pikun lenka .. everyone please follow his teachings for a successful bright future.. all the best ❤

Take any ant.

Place it on one of the vertex points

Make it walk around the polygon, along the sides

Ant generally walks in a straight line, except at a vertex where it quite naturally turns by a certain angle.

When it gets back to its starting point it will have turned a full circle: 360 degrees.

At each vertex, the internal angle at that vertex is 180 degrees minus the angle it turns at that vertex. Draw a picture or, better, make a mental model. Once you've seen it, it's obvious.

Therefore, 360 = 180n minus sum of internal angles.

Or in other words, sum of internal angles is 180n-360 which is 180(n-2).

What is this teaching for any specific exam?

[yalamasettiganesh]

The exterior angle is 45° in a polygon what is the sum of the interior angles in a polygon ??

[chethansistu]

180-no.of sides ÷ 360 = sum of the angles of that polygon
