The Green Triangle is an extremely rare Polygon in Diep.io, and the third strongest in regards to health. When killed, it rewards 2,500 XP to the player who deals the final shot. It is approximately 10 times stronger than a regular Triangle. The only two Polygons to be confirmed stronger than this one are the Green Pentagon and the Alpha Pentagon.
When the player is killed by this shape, the death screen will say “You were killed by: Triangle” instead of “You were killed by: Green Triangle”, much like every other Green Polygon in the game.
The Green Triangle is very similar to the regular Triangle if the player uses the Console on triangles.
The Green Triangle is the same size and shape as a regular triangle.
