Triangle
Consolidation in a narrowing range - breakout usually continues the prior trend.
Triangles (ascending, descending, symmetrical) form as volatility drops. Ascending: flat top + rising bottom = demand building. Descending: falling top + flat bottom = supply pressing. Symmetrical: both sides narrow - direction decided by the breakout. Breakouts usually continue the prior trend (~65%). Target = base height added to breakout point.
In plain words
Price squeezes - swings get smaller until it finally breaks clearly up or down. Usually continues whatever it was doing before.
Example
