  1. Geometry Using Paper Folding Lesson 1.4

  2. Definition • Perpendicular lines When two lines intersect at a right angle B AC BD C A D

  3. Definition • Parallel lines Two lines in the same plane that never intersect. AC BD A C B D

  4. Definition • Conjecture A statement that you think is true. An “educated guess” based on observation.

  5. Activity 1Perpendicular and Parallel Lines • What kind of lines are l and n? Perpendicular • What kind of lines are mandn? Parallel

  6. Conjecture • Complete the following conjecture about parallel and perpendicular lines: If two coplanar lines are perpendicular to the same line, then the lines are parallel.

  7. Definition Distance from a point to a line: the length of the perpendicular segment from the point to the line.

  8. Definition • Segment bisector A line that divides a segment into two congruent parts. B E C A D

  9. Definition • Midpoint The point in the middle of a segment. Divides the segment into two congruent parts. MIDPOINT C B A

  10. Definition • Perpendicular bisector a segment bisector that is perpendicular to the segment B C A E D

  11. Definition • Angle bisector a segment that bisects an angle. B D A C
