  1. Unit 6 Vocabulary 2010 Traversing Congruency

  2. Transversal • A line which intersects two or more lines.

  3. Congruent • Angles or segments that have the same measure.

  4. Vertical Angles • A pair of opposite congruent angles formed by intersecting lines.

  5. Complementary Angles • Two angles whose measures add to 90˚.

  6. Supplementary Angles • Two angles whose measures have a sum of 180˚.

  7. Alternate Interior Angles • A pair of angles on the inner sides of two lines cut by a transversal that are on opposite sides of the transversal.

  8. Alternate Exterior Angles • A pair of angles on the outer sides of two lines cut by a transversal that are on opposite sides of the transversal.

  9. Corresponding Angles • Angles formed by a transversal cutting two or more lines and that are in the same relative position.

  10. Adjacent Angles • Angles in the same plane that have a common vertex and a common side.

  11. Same- Side Interior Angles • Angles which are on the inside of a pair of parallel lines and are on the same side of the transversal.

  12. Same- Side Exterior Angles • Angles which are on the outside of a pair of parallel lines and are on the same side of the transversal.

  13. Coincidental • Two lines that lie on top of each other.

  14. Skew • Straight lines that do not intersect and are not in the same plane.

  15. Parallel Lines • Lines in a plane that do not intersect.- stay the same distance apart.

  16. Perpendicular Lines • Lines that intersect to form right angles.

  17. Intersecting Lines • Lines that cross at exactly one point.

  18. Linear Pair • Adjacent angles formed by two intersecting lines. The measure of these are always 180.
