    \documentclass [a4paper, 12pt] {article}

    \usepackage {amssymb}

    \begin {document}

    $\langle a, b \rangle$

    \end {document}

with tex, < and > should (ordinarily) be used
only to mean less than and greater than.

they are used in html as angle brackets, but
that's probably mainly because they are usually
on keyboards.

\langle and \rangle are the tex angle brackets;
they are shallower than < and > and can be
sized with \left and \right.
