You know when you see the representation of the x, y, z axes for Cartesian
co-ordinate system. You can make the symbol with your fingers, like you're
at a heavy metal concert. I need to make quarter round meet on the inside
of a closet. The trim goes up the inside laying vertically on the 90°
corners, and the same trim also meets going laying horizontally both left to
right and front to back. To trim out the top square of whiteboard, which is
the ceiling of the closet, and the peg board, the three sides. I know how
to cut a 90° corner from the same trim to do the back of a closet, but how
to put a third piece "normal" to those. Can you cut all 3 at an equal
angle, or do you have to cope one(s) into the other(s)?

p.s. The quarter round isn't just plain quarter round. I made my own. I
took a 3/8" beading bit to 1/2" x 1/2" plain quarter round, for a little
more class. Leaves a 1/16" lip. More or less the same idea.

Cope it. First piece cut square and installed tight. Second piece,
cut the trim on a 45, then cut off all of the mitered face with a
jigsaw - undercut it a little, install. Third piece, cut the trim on
45s both ways, jigsaw (noun made into a verb, sue me) off the mitered
faces - you'll be left with a little tongue that comes to a point,
install.

not clear to me, show me

understand cut square tight
understand 45 mitre
understand double 45 mitre and comes to point. Q) are we talking equal and
very pointy point?

Q) cut off mitre face /undercut , and cut off mitre face, respectively for
the 45, & double 45 (sorry I'm Canadian & therefore slightly French; hence
colour?):
in the first case, is cut off mitre face /undercut 2 steps, possibly at the
same time, and then are we talking exactly the same step(s) in the second
case

Q) I don't understand cut off mitre face /undercut; is this a curved cut?
I'm thinking....

It sounds like coping is new to you. Here's a primer on cope cuts:

Does that help?

If you can't get the pieces to cope well you might consider
setting a "plinth" in the corner. Cut a custom square block
slightly taller than your base trim. Each mold can then be square
cut to meet the block.

This isn't as bad/difficult as it seems.

Just treat each of the three surfaces (side, back, ceiling) as their own
individual 90-degree two-way join.

The 'simplistic way' is to simply cut each join at a 45 degree miter.
you'll have two such cuts on each piece of 'quarter round'. If the
corner angles are not _all_ a "perfect" 90 degrees, you'll end up with
minor (or maybe 'not so minor') gapping that will have to be 'filled'.

The 'right way' is to do 'coped' joints, instead of mitered ones.
One piece (typically the _back-ceiling_ piece) is put in full width,
with butt corners against the sidewalls.

the next piece (typically the side/ceiling) is then coped to fit snugly
against the back-ceiling piece.

Then the last piece (typically, the side/back) is then coped to fit
snugly, *first* against the back piece, and *second* against the side piece.
