Using Parentheses (Round and Square Brackets)
The usage of grammar braces follows a special set of rules that are fairly easy to learn. Braces, also known as or parentheses, can be round, square, curly, or angled.
Definition and Examples of Parenthesis
Whatever the material inside the parentheses, it must not be grammatically integral to the surrounding sentence. If it is, the sentence must be recast. This is an easy mistake to avoid. Simply read your sentence without the parenthetical content. If it makes sense, the parentheses are acceptable; if it doesn’t, the punctuation must be altered.
Angled brackets have limited usage in writing. They are only found in a reference page to denote a url address. According to recent changes, citations no longer call for urls in reference pages; so, the use of angled brackets is now optional.

Braces, brackets and parentheses are each slightly different in style; but, they each follow similar rules, which is why they may often be used interchangeably.
