Find the measure of the exterior angle shown; interior angles are
and
, and exterior angle is
Here is the theorem for exterior angles, and we will use it in order to solve this problem:
Exterior Angle Theorem
The measure of an exterior angle of a triangle
is equal to the sum of the measures of the
two nonadjacent interior angles.
so, in your case will be:
....move
to the left, and
to the right
