Alternate Interior Angle
Alternate interior angle generally forms a z pattern.
Alternate interior angle. These angles are called alternate interior angles. Image will be uploaded soon. C and f are alternate interior angles. These pairs are alternate interior angles.
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. Alternate interior angles definition. The converse of the alternate interior angle theorem states that. Alternate interior angles are the angles that are formed on opposite sides of the transversal and inside the two lines are alternate interior angles.
If two lines are cut by a transversal and the alternate interior angles are congruent then the lines are parallel. 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. The pair of blue and pink angles denotes alternate interior angles. Learn about alternate interior angles.
So there are actually two pairs. This video shows a proof of the alternate interior angle converse. In the above given figure you can see two parallel lines are intersected by a transversal.
