1. Draw triangle ABC so that angles A and B are both 42 degrees. Why should AB be longer than BC? Extend CB to E, so that CB = BE, Mark D on AB so that DB-BC then draw the line ED, which intersects AC at F. Find the size of angle CFD. 

2. You are given a square ABCD, and midpoints M and N are marked on BC and CD respectively. Draw AM and BN, which meet at Q. Find the size of angle AQB.
