Are two angle of a triangle that are not adjacent to the exterior angle
In a polygon there are no such angles.
Two angle are side tok be adjacent angles if they have common (1) vertex and (2) arm (3) uncommon interior
Extend any straight side of a shape. The angle made by that side with the adjacent side of the shape is an exterior angle. Its value is 180 degrees less the interior angle.
Adjacent
The interior angle of a polygon and its adjacent exterior angle can never be complementary.
Ah...
No. It is equal to the sum of the opposite interior angles.
No, they are supplementary, not complementary.
Are two angle of a triangle that are not adjacent to the exterior angle
A angle formed inside a polygon by two adjacent sides.
equal to 180°
This is known in geometry as an interior angle.
true
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.
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.
They are called supplementary angles.
