Parentheses (()), braces({}), brackets([]), and chevrons(<>). I concur.

Or, in British English, brackets(()), curly brackets({}), square brackets ([]).

And I’ve heard both “angle brackets” and “pointy brackets” (<>)

That would be fine if we could somehow magically change the English language so that this would universally match how people call these symbols around the world - but that's not likely to happen.
