Alternate Interior Angles Definition

The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior.

Alternate interior angles definition. They lie on the inner side of the parallel lines but the opposite sides of the transversal. Alternate interior angles theorem. Alternate interior angles are two congruent angles from different parallel lines one from l i one from o n.

L a r is an alternate interior angle with a r n i a r is an alternate interior angle with a r o. These angles represent whether the two given lines are parallel to each other or not. Notice that the two alternate interior angles shown are equal in measure if the lines pq and rs are parallel.

They lie on the inner side of the parallel lines but the opposite sides of the transversal. Alternate interior angles are created where a transversal crosses two usually parallel lines. So in the figure below if k l then 2 8 and 3 5.

More about alternate interior angles. If the two lines are parallel then the alternate interior angles are congruent. C and f are alternate interior angles.

In this example these are two pairs of alternate interior angles. Each pair of these angles are inside the parallel lines and on opposite sides of the transversal. D and e are alternate interior angles.

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. Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. Alternate interior angles are formed when a transversal passes through two lines.
