Triangle
A technical analysis pattern created by drawing trendlines along a price range that gets narrower over time because of lower tops and higher bottoms. Variations of a triangle include 'ascending' and 'descending' triangles. Triangles are very similar to wedges and pennants.

Investopedia Commentary
Technical analysts see a 'breakout' of this triangular pattern as either bullish (on a breakout above the upper line) or bearish (on a breakout below the lower line).
