Please help me with this question!
The picture shows a stand for keeping a synthesizer. The top surface of the stand is parallel to the base, as shown. Which expression about the angles p and q is correct?
A: m<p=m<q
B: m<q=180 degrees-m<p
C: m<p=2(m<q)
D: m<q=90 degrees-m<p
The less than signs stand for angles.
Which one do you think it is?
No clueeeee.

How about now?
What does that do? isn't that the same picture as the one in the question?
yes. I thought if I drew it out, it might look clearer.
I just don't understand anything about the question D:
Hmm... Okay then... I'll try my best to help you understand.
have you heard of corresponding angles?
yes it was in my lesson but I forget what they really are.
Let's take away the line so it's easier for you to see. |dw:1346354183326:dw|
Corresponding angles: 'the angles that occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.'
so it's not A?
In this case, the corresponding angle of q would be... |dw:1346354360998:dw|
