Can you now tell her that both have right angle corners and are therefore rectangles. Check your dictionary just in case we don't mean the same thing on opposite sides of the (non rectangular) pond!

  I tried to make that point to my high school geometry teacher. I think she finally told me to sit down and shut up!

  Prop spar size is 0.080" sq tapering to 0.035" sq from about 4.5 lb wood. Tubes are 0.078" dia formed on brass tube. BTW a square is a special case of a rectangle.

  That sounds like it may be easyier. May I ask what size spar you use
  for an 18" prop. And what size paper tube do you fit it into.
  Thanks
