PPT Lines

• Perpendicular lines are formed when two lines meet each other at the right angle or 90 degrees
• Parallel lines are parallel to each other and do not meet at any point
• Transversal line is a kine that passes through two parallel lines
• Theorem 3.2 Alternate Interior Angles: If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent.

  
• Theorem 3.1 Corresponding Angles: If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent.

  
• Theorem 3.3 Alternate Exterior Angles: If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

  
• Theorem 3.4 Consecutive Interior Angles: If two parallel lines are cut by a transversal, then the paris of consecutive interior angles are supplementary.
