A triangle in palmistry is exactly what it sounds like: three lines intersecting to form a triangular shape. Unlike crosses (often seen as obstacles) or grilles (obstruction), triangles are almost universally read as positive marks.
The meaning depends on the mount. A triangle on the Mount of Jupiter (below the index finger) suggests talent for leadership and public speaking. On the Mount of Apollo (below the ring finger), artistic or creative genius. On the Mount of Mercury (below the little finger), business acumen and financial skill. On the Mount of Venus (thumb base), romantic or diplomatic talent.
A triangle on the head line suggests exceptional mental ability. On the fate line, career success through special skill. On the heart line, emotional intelligence or healing ability.
