Alternate Interior Angle Definition

More about alternate interior angles.

Alternate interior angle definition. Alternate interior angles are created where a transversal crosses two usually parallel lines. If two parallel lines are cut by a transversal the alternate interior angles are congruent. When two lines are crossed by another line called the transversal 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.

The angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior. Each pair of these angles are inside the parallel lines and on opposite sides of the transversal. Alternate angles are congruent.

Formally alternate interior angles are two interior angles that lie on different parallel lines and on opposite sides of a transversal. Notice that the two alternate interior angles shown are equal in measure if the lines pq and rs are parallel. Alternate interior angles are the angles formed when a transversal intersects two coplanar lines.

The transversal crosses through the two lines which are coplanar at separate points. Alternate interior angles are formed when a transversal passes through two lines. Try this drag an orange dot at a or b.

The alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but the opposite sides of the transversal. From the above given figure 3 4 5 6 are the alternate interior angles.

Learn about alternate interior angles. So there are actually two pairs. Based on the position of the angles the alternate angles are classified into two types namely alternate interior angles alternate interior angles are the pair of angles on the inner side of the two parallel lines but on the opposite side of the transversal.
