3. PARALLEL LINES: Two lines that do not intersect and are coplanar.

4. SKEW LINES: Two lines that do not intersect and are non-coplanar.

5. PERPENDICULAR LINES: Two lines that intersect and form a right angle.

6. PARALLEL POSTULATE: Given a line and a point not on the line, there is exactly one line through the point that is parallel to the given line. AB P

7. PERPENDICULAR POSTULATE: Given a line and a point not on the line, there is exactly one line through the point that is perpendicular to the given line. AB P

8. 1 2 3 4 56 7 8 TRANSVERSAL TRANSVERSAL: a line that intersects two or more coplanar lines.

9. CORRESPONDING ANGLES (CA): Angles in the exact same position. 1 2 3 4 56 7 8 Angles of the same color are corresponding angles. 1 2 3 4 56 7 8 TRANSVERSAL

10. ALTERNATE INTERIOR ANGLES (AIA): Angles that lie between the two lines and on opposite sides of the transversal. 1 2 3 4 56 7 8 Angles of the same color are alternate interior angles. 3 4 56 TRANSVERSAL Interior angles are in the space between the two black lines.

11. ALTERNATE EXTERIOR ANGLES (AEA): Angles that lie outside the two lines and on opposite sides of the transversal. 1 2 3 4 56 7 8 Angles of the same color are corresponding angles. 1 2 7 8 TRANSVERSAL Exterior angles are in the space outside the two black lines.

12. CONSECUTIVE INTERIOR ANGLES (CIA): Two angles that lie between the two lines and on the same side of the transversal. 1 2 3 4 56 7 8 Angles of the same color are alternate interior angles. 3 4 56 TRANSVERSAL Interior angles are in the space between the two black lines.

13. 1 2 7 8 3 4 5 6 9 10 16 15 11 12 13 14 Identify the following angles:
