angle bracket

    Either of the characters "<" (less-than, ASCII
   60) and ">" (greater-than, ASCII 62).  Typographers in the
   Real World use angle brackets which are either taller and
   slimmer (the ISO "Bra" and "Ket" characters), or
   significantly smaller (single or double guillemets) than the
   less-than and greater-than signs.
