The measure of the exterior angle of a convex octagon is indeterminate.
Exterior angle = 360/80 = 4.5 degrees. Interior angle = 180 - 4.5 = 175.5 degrees. And, a regular polygon has to be convex.
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A convex polygon is one with no angle greater than 180 degrees. A non-convex polygon is one that is not without such an angle.

The following are angles in a convex quadrilateral: Angle A = 80 degrees Angle B = 98 degree Angle C = 70 degrees What is the measure of the missing angle?

Yes, the angle sums will be the same regardless of whether or not it is a convex polygon.
Any polygon that has an angle that is > 180º is a concave polygon. A convex polygon does not. e.g. All regular polygons are convex.
A convex angle is any angle of 180 degrees or less. So all angles less than 90 degrees are certainly convex angles, but so are the angles between 90 and 180 degrees.
In a non-convex (or concave) polygon, at least one interior angle is a reflex angle. An alternative definition is that if you take any two points inside a conves polygon, the line joining them is wholly inside the polygon.
An interior angle of a convex heptagon can have any value in the range (0, 180) degrees.
