  3. Identify Pairs of Lines and Angles Section 3.1

  4. Definitions • Two lines are parallel lines if they do not intersect and are coplanar. In other words , parallel lines do not intersect and run in the same direction. • Two lines are skew lines if they do not intersect and are not coplanar. In other words, skew lines do not intersect but don’t run in the same direction. • Two planes that do not intersect are called parallel planes.

  5. Definitions • Perpendicular lines are lines that intersect to form a right angle. • Perpendicular planes are planes that intersect to form a right angle.

  6. postulates • Parallel Postulate • If there is a line and a point not on the line, then there is exactly one line through the point parallel to the given line. • Perpendicular Postulate • If there is a line and a point not on the line, then there is exactly one line through the point perpendicular to the given line.

  7. Angles • A transversal is a line that intersects two or more coplanar lines at different points. • Two angles are corresponding angles if they have corresponding positions. • Two angles are alternate interior angles if they lie between the two lines and on opposite sides of the transversal.

  8. angles • Two angles are alternate exterior angles if they lie outside the two lines and on opposite sides of the transversal. • Two angles are consecutive interior angles if they lie between the two lines and on the same side of the transversal. • Two angles are consecutive exterior angles if they lie outside the two lines and on the same side of the transversal.

  9. Assignment • Go back and look at your notes • 1. Underline or highlight important terms • 2. Write questions to yourself in the left-hand column next to main ideas • 3. Cross out or erase any unneeded information and fill in any gaps that you missed. • 4. Write a 2-4 sentence summary at the bottom of your notes. • This will be checked for a homework grade tomorrow.
