Okay sy mash bumpers More graffin for uh for you
- 00:05
to do here and got a little diamond shaped thing
- 00:08
either Our which of the following lines is not a

line of symmetry for the given shape above What line
- 00:18
of symmetry is a line that divides a shape into

two mirror image halves Hey we're in luck The given
- 00:23
shape has several lines of symmetry with shapes cut in
- 00:26
half by a vertical line passing through the origin as
- 00:29
well as a horizontal line right They're passing through the
- 00:31
origin and this vertical line has equation x equals zero
- 00:35
right no matter what Why is x zero and the
- 00:38
horizontal line has the equation Why is zero always forever
- 00:41
Never well the shape could also be cut in half
- 00:44
by a forty five degree angle line going up right
- 00:47
there read y equals x or up and left at
- 00:51
why equals negative x So we've seen that every answer
- 00:55
choice except for why equals one is a line of
- 00:58
symmetry so that's the odd men out And if we
- 01:00
graft that horizontal line why equals one While we'd see
- 01:04
that it doesn't divide the shape into two symmetrical halves
- 01:08
it was more like you know someone just had an
- 01:10
accident with their carving knife or something All right so 00:01:13.162 --> [endTime] that's it we popped
