;Triangular( <Lower Bound>, <Upper Bound>, <Mode>, x )
:Creates probability density function of [[w:Triangular distribution|triangular distribution]] with parameters ''lower Bound, upper Bound, Mode''.
;Triangular(  <Lower Bound>, <Upper Bound>, <Mode>, x, <Boolean Cumulative> )
:If ''Cumulative'' is true, creates cumulative distribution function of triangular distribution, otherwise creates probability density function of triangular distribution.
; Triangular( <Lower Bound>, <Upper Bound>, <Mode>, <Variable Value> ): Calculates the value of cumulative distribution function of triangular distribution at ''Variable Value v'', i.e. the probability ''P(X≤v)'' where ''X'' is a random variable with triangular distribution given by parameters ''lower Bound, upper Bound, Mode''.
:{{Note| Returns the probability for a given ''x''-coordinate's value (or area under the triangular distribution curve to the left of the given ''x''-coordinate).}}
:{{example|1=<div><code><nowiki>Triangular[ 0, 5, 2, 2 ]</nowiki></code> yields ''0.4''.</div>}}
