In math terms, the sum of the external angles of a regular polygon is 360 degrees. Here, we have a 12-sided regular polygon which rotates until the image coincides with the preimage. That is 360/12 = 30 degrees (the outside angle). If it rotated thus 12 times, it would have made one complete rotation.

Solution. Verified by Toppr. Let ^i and ^e be the interior angle and exterior angle of a regular 12-gon. Then we take n =12 in the formula i = (n−2) n π. Hence the interior angle is. ^i = (12−2) 12 π = 10 12×180 =150o. Was this answer helpful?
The question would like to know the angles of rotation for a 12 sides polygon.
Question. Calculate the sum of angles of a polygon having 12 sides. 900∘. 1800∘. 1440∘. 720∘. A. 900∘. B.
Then, QR is 12 sided polygon,so. a =? n = 12. a × n = a × 12 = 360° a = 360 / 12we. a = 30° Therefore, angle between Q and R is 30° The diagonal " PR " form a triangle. like,PQR. we Know that, angle between PQ and QR are 90° and 30° angle between (PQ + QR + PR) = 180° BY, PUT THE VALUE OF PQ and QR. 90° + 30° + PR = 180° PR = 180 ...
Let A i, i = 1, 2, 3,.....21 be the vertices of a 21 − sided regular polygon inscribed in a circle with centre at O. If triangles are formed by joining the vertices of the 21 − sided polygon then
Twelve equal charges (q), are situated at the corners of a regular 12 − sided polygon (for instance, one on each numeral of a clock face). What is the net force on a test charge Q at the centre? ( Assume the distance between q and Q pair(s) to be L )
