So are the teeth on a crosscut saw. As you say they are
triangles (viewed from the top), the trailing edge of the
triangle is full width of the blade.

John look at a tooth. Rip is full width and is all there.
A crosscut is angle cut to make and half of the metal is gone.

The shape and use of the tooth is completely different.

The way to tell isn't to squint at the teeth; rather, make a cut and
look at the kerf. A ripsaw makes a flat-bottom kerf, because
the teeth are chisel-like with the edge perpendicular to the cut,
while crosscut teeth have alternate bevel (makes a 'W' bottom kerf).
