Which of the following is not true of a regular
- 00:05
hexagon Well to tackle this problem go over each answer
- 00:13
option one at a time to find incorrect ones right
- 00:16
Remember that regular polygons have a rotational symmetry equal to
- 00:20
their number of sides right tex six they're hex has

six eyes so a regular hexagon will have a rotation
- 00:28
symmetry of order six Well that means it has six
- 00:31
lines of symmetry left through there It'll have symmetry every
- 00:35
time it's spun sixty degrees since well three hundred sixty
- 00:39
divided by six equals sixty and it'll have symmetry when
- 00:42
we spin it sixty degrees one hundred twenty degrees one
- 00:45
hundred eighty degrees two hundred four degrees three hundred degrees
- 00:48
and three hundred sixty degrees Yeah so get rid of
- 00:50
sea there so that means a regular hexagon does not
- 00:53
have a rotational symmetry of order Five so a is 00:00:56.886 --> [endTime] the right answer here right Wrong one
