Then one of the alternate angles is an exterior angle equal to the other angle which is an opposite interior angle in the triangle. What are alternate interior angles in geometry - their definition, meaning, theorem and its converse explained with examples in real life The word ‘alternate’ is usually used with pairs of angles, to indicate that each is on opposite sides of a line. In the diagram given below angle 5 and 7, angle 6 and 8, angle 1 and 3 , angle 2 and 4 are the alternate interior angles. Alternate Interior Angles Definition.
