If possible, draw a line of symmetry in each of the following figures or words. If it is not possible to draw a line of symmetry
Marrrta [24]

Answer:

  a) none

  b) vertical through the middle

  c) horizontal through the middle

  d) none

Step-by-step explanation:

a) A repeated asymmetrical pattern rarely has a line of symmetry. (I can't think of a case where it does.)

__

b) This figure has left-right symmetry about its centerline. (In general, a light bulb will not, because the screw threads are asymmetrical.)

__

c) Each of the letters is symmetrical about its horizontal centerline, so  the word is as well.

__

d) The letter S is symmetrical about its center point, but not about any horizontal or vertical line. This word is not symmetrical about any line.

__
