Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle) Step 2: m∠p − m∠o = 90 degrees (alternate interior angles) Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p Step 4: So, m∠m + m∠n = m∠p In which step did the student first make a mistake and how can it be corrected? Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (corresponding angles) Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles) Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles) Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles)

@phi can you help me?

do you know a straight line is 180 degrees?
anonymous
  • anonymous
yes
phi
  • phi
do you see angle O and angle P ? do they make a line ?
anonymous
  • anonymous
yes they do so both angles would equal 180 degrees right?
phi
  • phi
in other words, if you faced toward B and then turn to face point A you would have turned angle O. then turn the amount of angle P. you would be looking backwards. that is 180 degrees
anonymous
  • anonymous
wait what does the turn mean?
phi
  • phi
an angle is how much you turn. for example if you look toward point A, and turn 180 degree you would be facing in the other direction.
anonymous
  • anonymous
oh ok
phi
  • phi
In this problem, if you look at point B and turn to look at point A in the picture, you turned "angle O". if you then turn the amount angle P, you would be looking in the opposite direction from point B anyway, we say angle O + angle P= 180 degrees
phi
  • phi
when two angles add up to 180 we call the supplementary angles (I guess you have to memorize that)
anonymous
  • anonymous
yea
anonymous
  • anonymous
so i guess it would be d
phi

the idea is

thx! i got it right!!!!!!!!!!!!! lol
