We had a shortened period today due to our first all school assembly. We spent our time going over the chapter 2 review sheet today and answered any questions that came up. We also went through one more proof together before getting started on the final review for the test on Monday. The answers to this second review will be posted on this blog on Sunday afternoon.

page 42 proof; #14
1. m angle SRT = m angle STR 1. given
2. m angle 1 + m angle 3 = m angle SRT
m angle 2 + m angle 4 = m angle STR 2. angle addition postulate
3. m<1 + m<3 = m<2 + m<4 3. substitution property
4. m<3 = m<4 4. given
5. m<1 = m<2 5. subtraction property =
page 65 proof; #9
1. <1 is supplemental to <3 1. given
<2 is supplemental to <3
2. m<1 + m<3 = 180 2. definition of supplemental
3. m<2 + m<3 = 180 3. definition of supplemental
4. m<1 + m<3 = m<2 + m<3 4. substitution / transitive
5. m<3 = m<3 5. reflexive
6. m<1 = m<2 6. subtraction prop. =
7. angle 1 congruent to angle 2 7. definition of congruence
8. line J is perpendicular to line K 8. if 2 lines form congruent
adjacent angles, then lines are
perpendicular
