1. Are the following triangles congruent? If yes, state the triangle congruence postulate, and identify the congruent triangles. Bell Ringer

2. Identify three sets of parallel lines in the classroom. Parallel lines Lines in the same plane that do not intersect

3. A line that intersects two or more lines in the same plane. What is a transversal? Congruent angles Two angles that have the same measure Topic: Angles

4. Complementary angles Two angles whose measures have a sum of 90 degrees Supplementary angles Two angles whose measures have a sum of 180 degrees <A + <B = 180 <1 + <2 = 90

5. Vertical angles Exterior angle Angles that are opposite each other when two lines intersect. < 1 and < 4 <6 and <5 When the sides of a triangle are extended, the angle that is adjacent to the interior angle

7. Find the measure of angles 1-8, if m<2 = 100 degrees and m<5 = 50 degrees Finding angle measures

8. Find the measure of angles 1-8 given m< 2 = 85 and m< 6 = 85

9. Nonadjacent interior angles that lie on opposite sides of a transversal Alternate interior angles <3 and <6 <4 and <5

10. Corresponding angles are the angle pairs that are in the same position and same side of the transversal. Corresponding angles <1 and <5 <3 and <7 <2 and <6 <4 and <8

11. Vertical angles Vertical angles are the angles that are opposite each other when two lines intersect <3 and <2 <1 and <4 <5 and <8 <7 and <6

12. Consecutive angles Are the angle pairs that are on the insides of the two lines (the interior) and on the same side of the transversal.transversal <3 and <5 <4 and <6
