Alternate Interior Angles

When two parallel lines are cut by a transversal the resulting alternate interior angles are congruent.

Alternate interior angles. In the above diagrams d and e are alternate interior angles. One way to find the alternate interior angles is to draw a zig zag line on the diagram. There are thus two pairs of these angles. These pairs are alternate interior angles.

In the figure above click on other angle pair to visit both pairs of alternate interior angles in turn. In the above given figure you can see two parallel lines are intersected by a transversal. C and f are alternate interior angles. Alternate angle theorem states that when two parallel lines are cut by a transversal then the resulting alternate interior angles or alternate exterior angles are congruent.

When two lines are crossed by another line the transversal a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal are called alternate interior angles. D and e are alternate interior angles. The alternate interior angles theorem states if two parallel lines are cut by a transversal then the pairs of alternate interior angles are congruent. Two separate straight lines can both be crossed by a third line called a transversal line.

The alternate interior angles theorem states that. If two parallel lines are cut by a transversal then the alternate interior angles are equal. Alternate interior angle generally forms a z pattern. Alternate interior angles exterior angles.

The pair of blue and pink angles denotes alternate interior angles. Learn about alternate interior angles. With each pair of alternate interior angles both angles are inside the parallel lines and on opposite alternate sides of the transversal. 24 june learn about alternate corresponding and co interior angles and solve angle problems when working with parallel and intersecting lines.

Alternate interior angles definition. Alternate interior angles are the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles. These angles are called alternate interior angles. Understanding alternate interior and exterior angles begins with becoming familiar with what is known as a transversal line.
