  1. 9-15 Honors Geometry Warm-up Complete #1-6 on the 1-4 Enrichment page in packet.

  2. HW: pgs. 34-36 #34-40, 42-44, 52-60 • 30o • 65o • 6 • 4 • 35o • 4 • The angle at which the dogs must turn to get the scent of the article is an acute angle 42. 60o, 30o, 90o, 60o, 120o, 60o • 31o, 59o • They are congruent indicated by the marks.

  3. 1-5 Angle Relationships • Adjacent Angles: two angles that lie in the same plane, have a common vertex, and a common side, but no common interior points • Vertical Angles: 2 nonadjacent angles formed by two intersecting lines. • Linear Pair: pair of adjacent angles whose noncommon sides are opposite rays.

  4. Complementary angles: two angles whose measures have a sum of 90o. • Supplementary angles: two angles whose measures have a sum of 180o

  5. Perpendicular Lines: lines form right angles
