And because the angles of a triangle sum to 180 degrees, angle is 90 degrees. It's also a right angle! Han: Oh! Then line and line are both perpendicular to the same line. That's how we constructed parallel lines, by making them both perpendicular to the same line. So lines and must be parallel.Algebra 2 Unit 1 Lesson 6 Illustrative Mathematics Answer Key.
