Indicate the (111) and ([11]0) ([11] has an over line, so is negative, dont know how to do on forums!) planes in a cubic lattice in a diagram, then calculate the angle between them.

3. The attempt at a solution

I think I have drawn this right (see attatchment), but Im not sure what angle it is refering to.

I would guess it is 90 degrees (in red), but I doubt I would be asked this, maybe the other angle (purple), could someone give any thoughts?

Also if my drawing is wrong, let me know! I wasn't 100% sure about the negative (110)
