Answer:
The sum of the interior angle measures of a triangle
is 180°. You can find the sum of the interior angle
measures of any n-gon, where n represents the
number of sides of the polygon, by multiplying
(n - 2) 180°. In a polygon, an exterior angle forms a
linear pair with its adjacent interior angle, so the
sum of their measures is 180°. In a triangle, the
measure of an exterior angle is equal to the sum of
the measures of its two remote interior angles.
