There are 3 Types of Triangle,
Triangle forms in Corrective waves,
Triangle occurs in wave 2, 4 & B,

1) Contracting Triangle
+ Always Subdivides Into Five waves
+ at least four waves among wave A, B, C, D, each subdivide
into a Zigzag or Zigzag Combination.
+wave C never moves Beyond the end of wave A, wave D never moves beyond the end of waves b and D converges with a line connecting the eds of waves A and C.
+A triangle never has more than one Complex sun wave, in which case it is always a zigzag combination or a triangle.

2) Expanding Triangle :
most Rules are same as for contracting triangle
differences is :
+ wave C, D and E each moves beyond the end of the preceding same- directional sub-wave.
+ sub-waves B, C and D each retrace the last 100%
but no more than 150 Percent of preceding sub-wave.

3) Barrier triangle :
+ a Barrier Triangle has the same characteristics as a contracting triangle expect that waves B and D end at essentially the same level.
We have yet to observe a 9-wave barrier triangle, implying that this form may not extend.
+ when wave 5 follows a triangle, it is typically either a brief, rapid movement or an exceptionally long extension.
