When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal.
What Are Alternate Interior Angles in Geometry? When a transversal crosses two parallel lines (or non-parallel lines), the pair of nonadjacent angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are known as alternate interior angles.
Learn what alternate interior angles are and how to identify them when a transversal cuts two parallel or non-parallel lines. See examples of congruent and non-congruent alternate interior angles and practice with fill-in-the-blank problems.
Alternate interior angles are the opposing pair of interior angles formed by a transversal and two parallel lines. Learn how to identify, measure and use them to show similarity for two triangles.
Alternate interior angles are a set of non-adjacent angles on either side of the transversal. In each diagram given below, two parallel lines are cut by a transversal. All the angle pairs highlighted in the same color represent alternate angles.
3 sie 2023 · Alternate interior angles are the pairs of angles formed when a transversal intersects two parallel or non-parallel lines. They are formed on the inner side of the parallel lines but on the opposite sides of the transversal.
