Question
In your own words, explain why an object that has more symmetry elements is said to have "higher symmetry" than an object with fewer symmetry elements. Identify the symmetry elements present in the following objects. (a) A ream of blank paper, no holes, (b) A ream of blank three-holed paper, (c) A round pencil, unsharpened, with cylindrical eraser, (d) A round pencil, sharpened, with cylindrical eraser. ldentify the symmetry elements present in the -following objects, (a) The Eiffel Tower. (You may have to look up a picture of it if you don't remember its shape!) (b) Any book (ignore the printing), (c) An octagonal wooden block, (d) A jack from the set of jacks pictured here:Explanation / Answer
13.2
a) Ream of blank paper: C2 axis of symmetry, v and h planes of symmetry, and a center of symmetry.
b) Ream of blank 3 holed paper: Only h plane of symmetry.
c) Round pencil, unsharpened with cylindrical eraser: Cinfinity axis of symmetry, and v plane of symmetry.
d) Round pencil, sharpened with cylindrical eraser: Cinfinity axis of symmetry, and v plane of symmetry (Assuming sharepened symmetrically).
13.3
a) The Eiffel Tower: C4 axis of symmetry, and v planes of symmetry.
b) Any Book (Ignoring printing): C2 axis of symmetry, and v plane of symmetry.
c) Octagonal wooden block: C8 axis of symmetry, v and h planes of symmetry, and a center of symmetry.
d) Picture is not available
