aum · Answer

#8) 
<2 is supplementary to <3
<5 = <2
Therefore, .....

aum · Answer

#9) Lines 'm' and 'n' are NOT parallel.
Therefore, the corresponding angles <9 and <6 ..... ?

anonymous · Answer

i have to look in geometry book for the theorems and postulates

anonymous · Answer

#8 is postulate 1-9 if two angles form a linear pair, then they are supplementary?

aum · Answer

#8 True.  Postulate:  Consecutive Interior Angles are supplementary.

anonymous · Answer

how'd you figure that out

aum · Answer

Click on "consecutive interior angles" and it will show which angles they are. You can click on others in the list too to learn corresponding angles, alternate interior angles, etc.: http://www.mathsisfun.com/flash.php?path=%2Fgeometry/images/parallel.swf&w=663&h=357&col=%23ffffff&title=Parallel+Lines%2C+and+Pairs+of+Angles

seen it before and didnt help

anonymous · Answer

that makes sense

aum · Answer

#9) <6 and <9 are corresponding angles but they will not be equal because lines m and n are NOT parallel lines.  Only for parallel lines the corresponding angles are equal.

anonymous · Answer

#10 is alternate interior correct?

aum · Answer

#10)  True.  Corresponding Angles.

anonymous · Answer

#11 converse ?

aum · Answer

#11) False.  Lines 'l' and 'n' are NOT parallel.  Therefore, <4 and <10, which form alternate interior angles, will not be the same because the lines 'l' and 'n' are not parallel.

aum · Answer

#12) False.  <4 and <6 are consecutive interior angles and therefore they are supplementary.  Not equal.

aum · Answer

#13) False.  <8 and <10 are consecutive interior angles BUT they will NOT be supplementary because lines 'm' and 'n' are NOT parallel.   Only for parallel lines, the consecutive interior angles are supplementary.

anonymous · Answer

whats consecutive mean

aum · Answer

See the diagram I drew earlier.

aum · Answer

anonymous · Answer

oh ok

aum · Answer

#14) False.  <4 and <9 are consecutive interior angles (Look at just the lines 'l' and 'n' and ignore line 'm').  But lines 'l' and 'n' are NOT parallel.  Therefore, the consecutive interior angles are NOT supplementary.

anonymous · Answer

it all has to do with supplementary

aum · Answer

Not sure what you mean.  Not ALL questions asked if the angles were supplementary.  Some asked if the angles were equal.

anonymous · Answer

that was a stupid statement dont pay attention to that
