MIRROR not working as expected.

Hi folks.
Introduction:
ABS(BEGINNER)!
I (also) do NOT have Fusion360 yet. I am in a club which have it and am just getting into designing from a student level.
I go to the group and am being "shown how to design things" and they use F360 on their machines, so I only get 2 hours a week to use it.
I was given a Windows 10 machine which I thought would be the answer to my needs of F360. But the installed O/S is 32 bit. Seems that is not supported. So I am going to have to do research there too.
THEREFORE I CAN'T SUPPLY SCREEN SHOTS OR ANY OTHER FILES.
(I use Ubuntu and I haven't found a F360 which installs on it. Though I have only had a quick look.)
So, to the "problem":
I have played with the MIRROR command on a 3D object and it seems to work. But that is only at THIS level.
Basic objects with holes, grooves, bumps, etc.
I then got into an object (say a rectangle) with a "flange"? at one end.
Say 10 degrees off vertical on one end.
I then select MIRROR and select the OBJECT. I then select the face which is flanged.
When I do this, I get a new object shown connected to the original object but now sticking into the "air" at 20 degrees (2 x 10).
GREAT! It works! Well, after this it all falls in a heap.
I make a triangle. Equilateral for now. No big deal. Say 40mm each side.
I then create an offset plane 150mm vertical.
On that plane I create another triangle (1mm / side).
I then LOFT the two together.
A pyramid - or what ever it is really called. But I hope you are with me to here.
Next: I make ANOTHER OFFSET PLANE 10mm above the first one.
I draw a square large enough to be bigger than the triangle.
I then extrude it up 140mm (CUT MODE) so all that is left is a 40mm triangle which is 10mm high.
I did it this way to get the "required angle" on the flange.
This is where it all falls apart.
I want to mirror that triangle to itself on one of the "flanged" sides.
I select the triangle (object) but can NOT select the side.
** Previously I could with the other object as stated above **
The ONLY mirror I can get is the top or bottom sides.
I have asked for help within the group but the best someone can do is to mirror it on the horizontal axis. Beyond that: They too are stuck.
Seems weird that F360 can't mirror this triangle at the angle.

Back story:
I am maybe going about this the wrong way - which is typical for me, but...... - I am wanting to create an:
Truncated icosahedron
(Sorry: cut/paste)
and have NO IDEA how else to make the triangles but to use radius distance to get the angle "draft" for the edges.
Now, I also know that equilateral triangles are not the ones needed, but where I am on the learning curve, I'm starting with making a triangle and mirroring it.
And that isn't happening.
If someone doesn't mind taking the time to help me with the maths to work out how to create said triangles for the "truncated icosahedron" it would be appreciated, but I feel that is not in the annex of this group.
