Answer:

An interior angle is an angle inside the shape. From the above diagram, we can say that the triangle has three interior angles.  In this triangle ∠ x, ∠y and ∠z are all interior angles. The sum of the interior angles is always 180° implies, ∠x + ∠y + ∠z = 180°. Let us see the proof of this statement.

An exterior angle of the triangle is the angle between one side of a triangle and the extension of an adjacent side. In the above triangle, ∠ a ∠b  ∠c are interior angles while ∠ d is an exterior angle.
