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".
The interior angle of a polygon and its adjacent exterior angle can never be complementary.
Ah...
An interior or exterior angle of the polygon.
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.
Measure them with a protractor
Very rarely.
The interior angle of a polygon and its adjacent exterior angle can never be complementary.
Ah...
An interior or exterior angle of the polygon.
No, they are supplementary, not complementary.
In a polygon there are no such angles.
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.
equal to 180°
With a protractor or if you know the exterior angle then it's 180 - exterior angle = interior angle
Measure them with a protractor
Interior angles are angles formed by two adjacent sides on the inside of a polygon. An exterior angle is the supplement of the interior angle.
It is: 180-exterior angle = interior angle because there are 180 degrees on a straight line
