if all the angles of a 18 sided polygons are equal,then
a.find the sum of is outer angles
b.what is the measure of one outer angle
c.what is the measure of one inner angle
Answers
✍Each exterior angle of an equilateral triangle is 120 degree and hence this the maximum possible value of exterior angle of a regular polygon. This can also be proved by another principle; which states that each exterior angle of a regular polygon is equal to 360 divided by number of sides in the polygon.......
✍( a ) . An alternative method is to use the exterior angle.

) , then each exterior angle is:360° / n = 360° / 18 = 20°
20°
20° The sum of the exterior and interior angles is
20° The sum of the exterior and interior angles is 180°
because they are adjacent angles on a straight line.
