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 outer side of each of those two lines but on opposite sides of the transversal. When two lines are crossed by another line (which is called the Transversal), the angles in matching corners are called corresponding angles. ... When the two lines are parallel Corresponding Angles are equal.Co-interior angles lie between two lines and on the same side of a transversal. In each diagram the two marked angles are called co-interior angles. If the two lines are parallel, then co-interior angles add to give 180o and so are supplementary.linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.Vertically Opposite Angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down.
