It is in the angle itself because in an angle there is the interior (part) the inside of the angle and the exterior (part) outside the angle and the angle itself so the vertex is in the angle it self it is neither exterior or interior

The measure of the exterior angle.

Are two angle of a triangle that are not adjacent to the exterior angle

Exterior angle+interior angle=180 degrees and 180-exterior angle=interior angle

Usually, the measure of an exterior angle of a pentagon is greater.

Very rarely.

No. The interior angle and exterior angle at the same vertex are supplementary. Each of them is (180 degrees minus the other). In rectangles (including squares), the interior and exterior angles at each vertex are both right angles.

The sum of an adjacent interior and its exterior angle will total to 360°. If the angles were to be equal, they would both have to be 180°. An angle of 180° is a straight line. A polygon may be composed of straight lines that intersect at vertices but a straight line has no vertex. That being the case, the answer to your question is "No".

20 degrees

60 degrees.

40

True

80 degrees.

Five of the six exterior angle measures of a nonregular hexagon measure 55, 60, 69, 57, and 57. what is the measure of the unterior angle adjacent to the sixth exterior angles?

The interior angle of a polygon and its adjacent exterior angle can never be complementary.

Exterior and interior angles at the vertex of a triangle add up to 180 degrees

It is in the angle itself because in an angle there is the interior (part) the inside of the angle and the exterior (part) outside the angle and the angle itself so the vertex is in the angle it self it is neither exterior or interior
