1. Draw the following: Line AB Line segment BC Ray FG

2. LEQ: How do we classify angles?

3.  An angle is the union of two rays that share a common endpoint.

4.  There are 4 ways to name an angle:   CED   DEC EE 33

5.  Acute angles have measures between 0 and 90 degrees

6.  Right angles have measures of exactly 90 degrees (indicated by a small square)

7.  Obtuse angles have measures between 90 and 180 degrees

8.  Straight Angle – an angle measuring 180 degrees

9. Right angle Straight angle Acute angle Obtuse angle

10.  Congruent angles are angles of the same measure(indicated by identical markings)

11.  Similar to the ruler postulate, if point B is in the interior of  AOC, then m  COB+m  BOA=m  COA  (<AOC)

12.  Vertical angles are opposite congruent angles created by the intersection of two lines <1 and <3 are vertical angles <2 and <4 are vertical angles

14.  Adjacent angles are angles that share a common side, common vertex, and no common interior points.  <KIH and <KIJ are adjacent angles

15.  Complementary angles are two angles who’s measures sum to 90 .  <TSU and <USV are complementary angles.  If m<TSU=42 , what is m<USV?  <TSU is the complement of <USV

16.  Supplementary angles are two angles who’s measures sum to 180 .  <TSU and <USV are supplementary angles.  <TSU is the supplement of <USV.  If m<TSU=120 , what is m<USV?

17.  Use the adjacent angles below to solve the following: m<HOK = 4x-6, m <KOB=6x+2, find x and m<HOK.

18.  Line up the bottom of the protractor with a side of the angle and center of angle with center of protractor. Extend the line of the other side and read the degree.
