The interior angle of a polygon and its adjacent exterior angle can never be complementary.
No, they are supplementary, not complementary.
Right angle, obtuse angle, acute angle, supplementary angle, complementary angle, interior angle, exterior angle, adjacent angle
Ah...
A supplementary pair.
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,
Are two angle of a triangle that are not adjacent to the exterior angle
always
Remote interior angles
In a polygon there are no such angles.
When any side of triangle is extended outwards then exterior angle is formed. Sum of this exterior angle and adjacent interior angle = 180o. If exterior angle = 180o(straight angle) then interior adjacent angle is 0o which is not possible. So exterior angle can't be straight angle.
