Two parallel lines are cut by a transversal. If one of the angles is a right angle, then the transversal is:

Class 7Transversal and Parallel LinesLines and Angles
  • Aperpendicular to both lines
  • Bparallel to both lines
  • Cperpendicular to one line only
  • Dat 45° to the lines

Step-by-Step Solution

If one angle is 90°, all angles are 90°, so the transversal is perpendicular to both parallel lines.
