Ancient Art, Modern Match
Welcome to Trine!
Trine is a synastry discovery engine. We use your complete birth chart to find your absolute most compatible matches around the world.
We look beyond your Sun, Moon and Rising. Trine analyzes 81 planetary aspects to connect you with your strongest matches.
— Synastry —
Synastry is the traditional method of compatibility analysis in Astrology. It analyzes the angles ('aspects') between all planets in two birth charts.
Aspects correspond to certain relationship patterns based on the planets and signs involved.
The Planets: Sun, Moon, Ascendent, Mercury, Venus, Mars, Jupiter, Saturn, Midheaven
The Signs: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces
The Elements: Fire, Earth, Air, Water
The Aspects:
Conjunction –- 0° (Amplifying)
Sextile ––––– 60° (Supporting)
Trine ––––––120° (Harmonizing)
Square ––––--90° (Challenging)
Opposition ––––180° (Polarizing)
When you hear "fire signs are compatible”, Synastry explains it’s because they are in Trine (Aries, Leo, and Sag are each 120ª apart).
