my trifix is said to be 2w1, 6w5, 9w1.
==================
You are a Type 2 with a 1 wing: "The Helper Idealist" 
Your trifix is 2w1, 6w5, 9w1. 
In enneagram theory, you have one type for how you relate to the world (either 8, 9, or 1), one type for how you think (5, 6, 7) and one type for how you see yourself (2, 3, 4.) Your tri-fix contains one number from each of these triads. They are listed in the order of how strongly they present in your personality. 
Your core type (your strongest type) is Type 2 with a 1 wing: Type Two individuals are generous and kind. Twos love others and want to be loved, and becoming close to others is a theme in the life of the Two. This is why Two is often referred to as the Helper type – because they keep coming, time and time again, to the aid of others. Out of all the types in the Enneagram, Twos are the most likely to help someone when they’re feeling down or when they’re being attacked. When a Type Two is stressed, they can become aggressive like an unhealthy Type Eight. When they’re healthy, a Type Two becomes emotionally aware like a healthy Type Four. You are a Type Two with a One wing, which means that the helpful nature of the Two combines with the idealistic nature of the One to make a very humanitarian personality. 
Your second type (your next strongest type) is Type 6 with a 5 wing: Type Six individuals are reliable, committed, and security-oriented. They are natural troubleshooters, and are always aware of potential problems. This makes the Type Six anxious, but the anxiety fuels them to resolve their problems. They can range from loyal to rebellious, depending on where they get their security from – if the security is from within, they can be very defiant… if it comes from others, they can be very cooperative and devoted. When a Type Six is in a growth state, they become calm like a Type Nine. When they are stressed, they can become arrogant like an unhealthy Type Three. You are a Type Six with a Five wing, which means that the committed nature of the Six combines with the cerebral nature of the Type Five. As a result, you often excel at concrete thinking and troubleshooting. 
Your third type (the least-used of the three) is Type 9 with a 1 wing: Nines are receptive, easygoing, and loveable. Out of all the types in the Enneagram, they have a special ability to get along with others. For this reason, they’re often skilled mediators, resolving conflicts both within themselves and among others. Nines value peace, especially inner peace, very highly. When in a state of growth, Nines become energetic and driven like Type Threes. When stressed, Nines become anxious like an unhealthy Type Six. You are a Type Nine with a One wing, which means that the harmonious traits of the Type Nine merge with the idealistic nature of the Type One. You have an idealized view of the world, and your drive toward harmony is one way to fulfill that dream. 
Some words that describe you: relaxed, peaceful, harmonious, generous, helpful, selfless, loving, loyal, reliable, anxious, skeptical.
