All right, so we are looking at a couple of different things asking if they've got objects of symmetry.
00:06
The first we're looking at is a circular clock face.
00:09
Now the circular part itself obviously will have an axis of symmetry.
00:14
However, with the circular clock face, you have to consider that there's also the numbers on each side.
00:19
And therefore, since the numbers are different, there's going to be no axis of symmetry.
00:24
There's no way you can cut this in any way so that it's going to be symmetrical about both sides.
00:31
All right, the next is going to be a football.
00:34
Now, i'm assuming this means an american football, but it will work equally well as a soccer ball because both do have a plane of symmetry.
00:47
All right, so for part c, we're asking about a dime.
00:50
Now, again, since it's circular, you would think that there is a good chance this does have an axis of symmetry.
00:55
But especially with the dime, or i'm assuming an american dime, obviously you've got the picture or the face on the front of it...
