Definition alternate interior angles. Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. Alternate interior angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal. More about alternate interior angles.

Use the z test to confirm alternate angles. D and e are alternate interior angles. Try this drag an orange dot at a or b.

The transversal crosses through the two lines which are coplanar at separate points. Alternate interior angle generally forms a z pattern. Alternate interior angles are the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.

Alternate interior angles are created where a transversal crosses two usually parallel lines. Alternate interior angles are formed when a transversal passes through two lines. They lie on the inner side of the parallel lines but the opposite sides of the transversal.

Each pair of these angles are inside the parallel lines and on opposite sides of the transversal. They lie on the inner side of the parallel lines but the opposite sides of the transversal. The alternate interior angles are the angles formed when a transversal intersects two coplanar lines.

When two lines are cut by a transversal the pair of angles formed interior of the two lines and on the opposite of the transversal is called alternate interior angles. Notice that the two alternate interior angles shown are equal in measure if the lines pq and rs are parallel. C and f are alternate interior angles.
