Answer 2

Answer:

For n sided regular polygon, each of the internal Angles = $\frac{1}{n}$(180°n - 360°)

Step-by-step explanation:

If the number of sides of a regular polygon is 3 (n=3),

then Sum of the internal angles = 180° = 1 x 180° = (3 - 2) x 180°

If the number of sides of a regular polygon is 4 (n=4), connecting a diagonal we get two triangles:

then Sum of the internal angles =2 x 180° = (4 - 2) x 180°

If the number of sides of a regular polygon is 5 (n=5), connecting two diagonals from single vertex, we get three triangles:

then Sum of the internal angles =3 x 180° = (5 - 2) x 180°

Similarly, If the number of sides of a regular polygon is n, connecting (n-3) diagonals from single vertex, we get (n-2) triangles:

then Sum of the internal angles =(n-2) x 180°

∴ Each of the internal Angles will measure:

= $\frac{(n-2)}{n}$ x 180° = $\frac{1}{n}$(180°n - 360°)
