Question

which describes the relationship between the measure of the exterior angle of a triangle and the measures of the remote interior angles of the triangle?
the sum of the measures of the two remote interior angles is equal to the measure of the exterior angle.
the sum of the measures of the two remote interior angles is double the measure of the exterior angle.
the sum of the measures of the two remote interior angles is half the measure of the exterior angle.
the sum of the measures of the two remote interior angles is equal to 180°.

Explanation:

The exterior - angle theorem of a triangle states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non - adjacent (remote) interior angles.

Answer:

The sum of the measures of the two remote interior angles is equal to the measure of the exterior angle.
