# Indent paragraph after definition

I'm looking to accomplish something like this (example done in Word):

Basically, after a heading, every line should be spaced a varied amount. Please let me know if there is a package which supports this. Thank you.

• Will all your definitions have to be automatically numbered, i.e. is it a theorem-like structure? – Bernard Jan 11 '18 at 9:24
• @Bernard That would work as well... – user147592 Jan 11 '18 at 13:15

The hanging package provides support for hanging indents.

The hang­ing pack­age fa­cil­i­tates the type­set­ting of hang­ing para­graphs.

The pack­age also en­ables type­set­ting with hang­ing punc­tu­a­tion, by mak­ing punc­tu­a­tion char­ac­ters ac­tive. This fa­cil­ity is best sup­pressed (it can in­ter­fere with other pack­ages) — there are pack­age op­tions for sup­press­ing each in­di­vid­ual punc­tu­a­tion char­ac­ter. ‘Real’ at­tempts at hang­ing punc­tion should nowa­days use the mi­crotype pack­age, which takes ad­van­tage of the sup­port of­fered in re­cent ver­sions of pdfTeX.

Use the command \hangpara{<indent>}{<afternum>} at the start of the paragraph, where <indent> is the length to indent the paragraph by, and <afternum> is the number of lines to not be indented at the start of the paragraph (in your case, 1).

However, you mention hanging indents after headings, in which case the description environment, which is a part of base LaTeX, might be more appropriate.
