The interior angles measure 360 degrees.
If interior measure means interior angles, their sum is 360 degrees. Also, whether the figure is convex is irrlevant.
A polygon is a closed plane figure bounded by straight sides. Since it is a closed surface, it has an interior (inside) and an exterior (outside). The interior angle of a polygon is the angle formed by two adjacent sides such that the angle is facing the interior of the polygon.
The angles have the same measure. In the reflection the order of the angles are changed from clockwise to counterclockwise.
2160 degrees (14-2)*180 = 2160

I believe it's 1,800 degrees.
The angles have the same measure. In the reflection the order of the angles are changed from clockwise to counterclockwise.
