Questions & Step-by-Step Solutions

If two parallel lines are cut by a transversal and one of the exterior angles is 120 degrees, what is the measure of the opposite exterior angle?
  • Step 1: Identify the two parallel lines and the transversal that cuts through them.
  • Step 2: Recognize that when a transversal cuts parallel lines, it creates pairs of angles.
  • Step 3: Understand that exterior angles are the angles formed outside the parallel lines.
  • Step 4: Note that opposite exterior angles are equal to each other.
  • Step 5: Since one exterior angle is given as 120 degrees, the opposite exterior angle must also be 120 degrees.
