Please help me with this question!

OpenStudy (anonymous):

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?

OpenStudy (anonymous):

A: m<p=m<q

OpenStudy (anonymous):

B: m<q=180 degrees-m<p

OpenStudy (anonymous):

C: m<p=2(m<q)

OpenStudy (anonymous):

D: m<q=90 degrees-m<p

OpenStudy (anonymous):

The less than signs stand for angles.

OpenStudy (anonymous):

Which one do you think it is?

OpenStudy (anonymous):

No clueeeee.

OpenStudy (anonymous):

How about now?

OpenStudy (anonymous):

What does that do? isn't that the same picture as the one in the question?

OpenStudy (anonymous):

yes. I thought if I drew it out, it might look clearer.

OpenStudy (anonymous):

I just don't understand anything about the question D:

OpenStudy (anonymous):

Hmm... Okay then... I'll try my best to help you understand.

OpenStudy (anonymous):

have you heard of corresponding angles?

OpenStudy (anonymous):

yes it was in my lesson but I forget what they really are.

OpenStudy (anonymous):

Let's take away the line so it's easier for you to see. |dw:1346354183326:dw|

OpenStudy (anonymous):

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.'

OpenStudy (anonymous):

so it's not A?

OpenStudy (anonymous):

In this case, the corresponding angle of q would be... |dw:1346354360998:dw|
