In any triangle exterior angle plus interior angles = 180 degrees

A isosceles right angle triangle will have 2 equal interior angles of 45 degrees and 1 angle of 90 degrees with its largest exterior angle being 180 -45 = 135 degrees.

...a right triangle.

The exterior angles of a regular n-gon measure 360/n degrees each and each interior angle is supplementary to its corresponding exterior angle. Thus each exterior angle measures 360/17 degrees which is approximately equal to 21.176 degrees. Each interior angle will then measure 180 - 360/17 degrees which is approximately equal to 158.824 degrees.

Yes, because it is equal to the sum of the two of them.

The opposite exterior angle.

No. It is equal to the sum of the opposite interior angles.

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,

The exterior angle of a triangle is equal to the sum of the two opposite interior angles. So if a triangle had points A, B and C: The exterior angle at B would equal the sum of interior angles at A and C. Similarly, the exterior angle at C would equal the sum of interior angles at A and B And the the exterior angle at A would equal the sum of interior angles at C and B.
