Triangles are a correction five-wave pattern (marked as A-B-C-D-E), which is divided into five types. This pattern is formed in a position prior to the final wave in an impulse or a correction. For example, a triangle could be formed in a wave four in an impulse or wave B in a zigzag. Also, this pattern occurs in final wave X in a double/triple zigzag or three...
