The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle?

Very rarely.


Is the measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle?

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.


Does the measure of an exterior angle at the vertex of a polygon equal the measure of the adjacent interior angle?

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".

What is an angle formed by one side of the triangle and the extension of an adjacent angle?

Is the vertex of an angle in its exterior?

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


What type of an interior angle of a polygon and its adjacent exterior angle are complementary?

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