Parallel lines Ay B and C D are intersected by a transversal line. Where the transversal intersects line Ay B is a ray that extends and intersects line C D. Where the transversal intersects C D is angle 2 to the upper left. Where it intersects Ay B are angles 5, 62 degrees, and 1 to the upper left, upper right, and lower left, respectively. The lower right angle at this intersection is divided into 2 angles by the ray: angle 6 and a right angle. Where the ray intersects line C D are angles 3 and 4 to the upper left and upper right, respectively.
