2D: How do I get a plane to be oriented properly?

I am in 2D view with an orthogonal camera pointing down the Z axis from negative to positive.

I create a plane and it is invisible.
In order for it to oriented properly I have to rotate y = 90 and z = -90 (or the negative of both).

After I do that, in order to scale it on the screen’s y axis I have to change the z scale value.

What the heck am I doing wrong?
(I’m feeling very stupid and frustrated at the moment!)

Thanks for any help.

Create a quad instead. Or a sprite.
