They are all 60 degrees.
No because they add up to 180 degrees
-- A scalene triangle has three interior angles and three exterior angles. -- The sum of the interior angles is 180 degrees, and no two of them are equal. -- The sum of the exterior angles is also 180 degrees, and no two of them are equal. -- The sum of each interior angle and its adjacent exterior angle is 180 degrees.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,

Because it has eight sides it is an octagon so:- Exterior angles: 360 degrees Interior angles: 1080 degrees
They equal the supplement of the interior angle it is adjacent to. (180-int. angle) E.g: the exterior angles of an equilateral triangle are each equal to 120 degrees.

Yes. Combined, they would form a straight line, or 180 degrees.
No because an exterior angle and an interior angle of a polygon add up to 180 degrees but exterior angles around a polygon add up to 360 degrees
Exterior angle 40 degrees Interior angle 140 degrees
Interior angles are 180 degrees Exterior angles are 360 degrees
