Neutral Geometry
Need some help in neutral geometry.
The first one is to prove that parallelograms exist.
(the others depend on this proof so hopefully getting this will help me do those) I started by using a saccheri quadrilateral and using triangle congruences to prove it but i get stuck.
Thanks -

Re: Neutral Geometry
I'm probably being unhelpful, but couldn't you draw a parallelogram and then prove that your drawing is a parallelogram (thus showing that a parallelogram exists)?
Why did the vector cross the road?
It wanted to be normal.
