Answer 2

@DanJS

Answer 3

It is reflected over a vertical line through the center for sure

Answer 4

line thats it?

Answer 5

point symmetry means it will look the same from all directions i believe

Answer 6

like if you flipped it upside down, is it the same?

Answer 7

nope

Answer 8

what does plane symmetry mean?

Answer 9

A plane of symmetry is an imaginary plane that bisects a molecule into halves that are mirror images of each other.

Answer 10

My first thought, is that it is the 3-D analogue to Reflection in @-D

Answer 11

ahh, so i am right

Answer 12

it is like reflection symmetry in 2 dimensional space

Answer 13

i am not sure, can you include plane symmetry here on this 2-d graph? You can imagine a second plane coming straight out at you perpendicular to the page, and through the middle of the tree, then it would be plane symmetry, just like it was line symmetry

Answer 14

so its line and plane?

Answer 15

i would just say line, plane i think is for 3-d objects.
Are some of the probs you do with symmety 3 dimensional things?

Answer 16

ok thnx

Answer 17

Symmetries of geometrical figures. Some of these are reflection groups, e.g., the group of symmetries of the square or the rectangle. The symmetry group of a swastika or any similar figure without an axis of symmetry is a rotation group.

Answer 18

That is one part of PLANE symmetry meaning, so yeah include Plane too
