We go through 2 examples. -17 is irrelevant here Hence the. Since it has equal sides it is an equilateral heptagon.

N 360 E. Regular octagon A regular octagon Type. Here nn-32 170 diagonals or nn-3 340 n23n-340 0 n-20n17 0 so n 20.

So the total number of diagonals become n n 32. 1 with the sum of the interior angles and the other with. 174 n - 2 180 n 174n 180 n - 2 87n 90 n - 2 2 n - 87n 90 2 90n - 87n 90 2 3n 9 n 3.

Interior Angle Degrees 180 - E. Do polygons have 8 sides. N2 3n -2K 0.

The line segments present on. Each interior angle of a regular polygon is 174⁰. Find the number of sides of polygon.

In a regular polygon the number of sides 360 size of the exterior angle We can use all the above facts to work out the answers to questions about the angles in regular. E Exterior Angle Degrees. The polygon has seven sides and hence seven angles.

A polygon of n-sides has nn-32 diagonals. We have to find the number of sides the polygon has. Sum of angles of polygon 16.

We know that a polygon with seven sides is called a heptagon. Hence it is an 11-sided. All the sides of the polygon are connected with the line segments.

Given that Exterior angle 45 Let number of sides n In a regular Polygon Sum of the exterior angles 360 Exterior Angle Number of sides 360 45 n 360 n 360.
