![]() ![]() If and only if the two angles of any pair of consecutive interior angles of any transversal are supplementary (sum to 180°), two lines are parallel. Have unique vertex points, are both inside, and are on the same side of the transversal. The two sets of angles that make up consecutive interior angles are: If and only if the two angles of any pair of matching transversal angles are congruent, two lines are parallel (equal in measure). The vertex points are distinct, they are on the same side of the transversal, and one angle is internal while the other is exterior. The four pairs of angles that correspond to each other are known as corresponding angles. All eight angles are right angles in this scenario. If one pair’s two angles are congruent (measured in the same way), then the angles of the other pairs are likewise congruent.Ī perpendicular transversal is a transversal that intersects two parallel lines at right angles. The four pairs of angles that make up alternate angles are:īoth angles are interior or exterior, have unique vertex points, located on opposite sides of the transversal, and both angles are internal or exterior. these types of angles on a transversal are given following: Angles of a transversalĪ perpendicular transversal is a transversal that intersects two parallel lines at right angles. ![]() ![]() If the two lines are parallel, successive interior angles are supplementary, comparable angles are equal, and alternative angles are equal, according to Euclid’s parallel postulate. DefinitionĪ transversal is a line that crosses two lines in the same plane at two different locations in geometry. When a transversal intersects two lines, it forms a variety of pairings of angles, including consecutive interior angles, consecutive exterior angles, matching angles, and alternative angles. Transversals are used to evaluate whether or not two or more than two lines in the Euclidean plane are parallel. ![]()
