Postulate 11: (Corresponding Angles Postulate) If two parallel lines are cut by a transversal, then the corresponding angles are congruent. A transversal is a line that Geometry (Part 1) Lines and angles A line is an infinite number of points between two end points. Two straight lines are cut by a transversal so that the co-interior angles are equal. Parallel lines are non-intersecting lines, Corresponding angles are equal line cutting across two parallel lines creates four pairs of equal corresponding angles, as shown in the diagram below: Note: You may also have heard these The second theorem: the one that tells you that parallel lines always have certain angle properties, is true only in Euclidean geometry. Diagram not drawn to scale. Alternate angles are pairs of angles that lie inside the parallel lines on alternate sides of the transversal. 5. Use the Transitive Property of Parallel Lines to explain why the leftmost pole is parallel to the rightmost pole. Let us quickly recapitulate the angle relationships for the parallel lines cut by a transversal. When parallel linesare intersected by another line, it produces angles with important properties.
