interior angle the angle between adjacent sides of a rectilinear figure.

_____________

A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8. ... The central angle is 45° ( radians).

, an icosagon or 20-gon is a twenty-sided polygon. ... One interior angle in a regular icosagon is 162°,

Answer 2

welcome to the concept of geometry....
