need to find the line going through the middle of a parallelogram (solved)

[cosmic rain]

Sorry for bad picture, I have massacred the one on the paper. Please help. This is GCSE maths btw if that helps??

[bronze gulch]

what?

what are u supposed to find?

[cosmic rain]

the line going through

[hard mica]

Use the cosine theorem for the triangle FGE.

[bronze gulch]

oh

ok

[hard mica]

I assume the diagonal.

It does go through the center of the parallelogram, after all.

[cosmic rain]

but how do I find out the angles FEG and FGE

[hard mica]

No need. Or do you also need to do that?

[cosmic rain]

no i don't

oh, i'm being stupid

I misread the cosine rule

[hard mica]

Oh. Well, if you still want to, then after you find the diagonal, you can use the sine theorem to find the angles.

[cosmic rain]

Thank you very much

[hard mica]

You're welcome!

[cosmic rain]

Do I need to delete this now? or do I change the title or something?

[hard mica]

Eh, don't worry about it.

[cosmic rain]

alright, thanks
