Subject: How is it possible to see a crescent moon and the sun in the same sky?

The moon shines because the sunlight is reflected from its surface.  When there 
is a waxing/waning moon we can still see the sun.  The geometry involved is 
difficult to understand.  How can the crescent be visible at a 45 degree angle 
to the west and the sun be at its noon position?  The angles do not seem to 
correspond and I have difficulty explaining it because I have difficulty 
understanding the geometry involved.
