What would a math teacher think the right answer is?
\n" ); document.write( "I'll give you my guesses, but think of words mentioned in class.
\n" ); document.write( "
\n" ); document.write( "1.pencil _ I have some pencils shaped like hexagonal \"highlight%28prism%29\"s, and some other pencils shaped like \"highlight%28cylinder%29\"s, so that's what a pencil suggests to me, but
\n" ); document.write( "maybe the teacher thinks that a pencil suggests a line \"highlight%28segment%29\".
\n" ); document.write( "2.beam of light - \"highlight%28parallel%29\" lines. The sun is so far away that the sun rays are parallel. If it is the beam of light from a spotlight, it would suggest a \"highlight%28cone%29\" to me; and the spot of light would suggest a \"highlight%28circle%29\".
\n" ); document.write( "3.edge of a box _ a line \"highlight%28segment%29\"? a \"highlight%28line%29\"? a \"highlight%28dihedral%29\" angle?
\n" ); document.write( "4.clothesline _ a \"highlight%28line%29\" (although I you had studied Calculus, you would say a catenary)
\n" ); document.write( "5.cover of a book _ a \"highlight%28rectangle%29\" (I would not say a \"highlight%28plane%29\" , because planes go on forever in all directions and the cover of a book is small, but I don't know what the teacher thinks)
\n" ); document.write( "6.tip of a pencil _ The shape of a sharpened tip is a \"highlight%28cone%29\", but maybe the teacher sees a \"highlight%28point%29\" in the pointy end of the pencil
\n" ); document.write( "7.top of a table _ a \"highlight%28plane%29\" (The top of the table does not go on forever, but it goes on for white a length)
\n" ); document.write( "8.speck of dust _ a \"highlight%28point%29\"
\n" ); document.write( "9.edge of this page _ a line \"highlight%28segment%29\" because a whole line goes on forever in both directions
\n" ); document.write( "10.a sheet of paper _ a \"highlight%28rectangle%29\" , but maybe the teacher thinks of an endless \"highlight%28plane%29\"
\n" ); document.write( "11.sunlight _ I think of \"highlight%28parallel%29\" lines again.
\n" ); document.write( "12.table cloth _ I'm stumped. A curved \"highlight%28surface%29\" ?
\n" ); document.write( "13.intersection _ \"highlight%28angles%29\" ? \"highlight%28perpendicular%29\" lines?
\n" ); document.write( "14.tip of a ballpen _ a \"highlight%28sphere%29\" ? a \"highlight%28point%29\" ?
\n" ); document.write( "15.floor _ a \"highlight%28plane%29\"
\n" ); document.write( "
\n" ); document.write( "Good luck. Smile. You may get puzzling assignments like this from time to time. \n" ); document.write( "
\n" );
