An upside-down triangle (∇, nabla) symbolizes different concepts, most commonly representing the feminine, water, or earthly elements in spirituality/alchemy, a vector derivative (gradient) in math/physics, or, recently, a symbol for resistance/protests in the Palestinian context (derived from Hamas usage). Its meaning depends heavily on the context, ranging from scientific operators to cultural or political statements.
The upside-down capital delta symbol. , also called "nabla" used to denote the gradient and other vector derivatives. The following table summarizes the names and notations for various vector derivatives.
Some people regard it as a Satanic symbol because it is in some sense the Christian one in reverse. Traditionally, however, it's actually a symbol of the pope. This is because of the following legendary (and dubious) beliefs: What does a triangle in a circle mean?
Protestors' usage of the symbol originates from combat footage published by Hamas during the war that uses inverted red triangles as arrows to indicate Israeli military targets, such as tanks, shortly before they are attacked or destroyed. This in turn derives from the red triangle that appears on the Palestinian flag.
27. The upside-down smiley face 🙃 The upside-down smiley face is all, “Who, me?” It's a great way to accent a text to acknowledge that you're being silly, or to add a flirty spin to an otherwise serious conversation.
The inverted triangle🔻is a symbol of divine feminine energy. In Hinduism, it's associated with the goddess Devi, who embodies Shakti. In Buddhism, it's called Pahana, representing the journey from ignorance to enlightenment.
Upside-down triangle Inverted triangles are thought to symbolize womanhood, motherhood, and the moon. This contrasts directly with upright triangles, which represent the sun and masculinity. Double triangle Double triangles (or two triangles overlapping) carry unique meanings to different people.
The "▼" symbol is known as the Black Pointing-Down Triangle or a Down Black Triangle. It represents a downward direction or expandable content. In UI design, the down-pointing triangle symbol can replace "Expand" buttons in Figma Dropdowns and "Sort descending" indicators in data table headers.
At the very least it is disrespectful and is often considered as a satanic or anti-Christian symbol. Certainly, some denizens of popular culture have used it in films, music videos, album covers and stage costumes to represent Satan or the Antichrist.
There is a Zen saying “the world is upside down.” It means the way we look at the world is actually the complete opposite of what it really is. The idea is, somewhere along the line, we flipped the spiritual meaning of life.
Del, or nabla, is an operator used in mathematics (particularly in vector calculus) as a vector differential operator, usually represented by ∇ (the nabla symbol). When applied to a function defined on a one-dimensional domain, it denotes the standard derivative of the function as defined in calculus.
The upside triangle (called 'del') indicates the gradient. When you follow del with a dot, it means divergence .
The grassroots way views power as flowing upwards: this is the upside-down triangle. In this way of viewing power, the oil executive or head of state is inherently unstable. Like an upside-down triangle, unjust power and authority is unstable and will fall.
The nabla is a triangular symbol resembling an inverted Greek delta: or ∇. The name comes, by reason of the symbol's shape, from the Hellenistic Greek word νάβλα for a Phoenician harp, and was suggested by the encyclopedist William Robertson Smith in an 1870 letter to Peter Guthrie Tait. ∇

“The inverted triangle is a symbol of feminine power, the creative essence of the universe [Shakti]… The triangle pointing upwards is symbolic of the male principle (Purusha).
After speaking of the triangle (Colossians 1:4-5), Paul goes on to say, "Walk in a manner worthy of the Lord to please him in everything. Bear fruit in every good work and increase in the knowledge of God..." (Colossians 1:10-11).
The symbol for Earth as one of the four classical elements in alchemy is an upside down triangle with a line through it. Earth is used in rituals when a Wicca practitioner is drawing attention to the divine feminine, motherhood, growth, life, and/or nature.
The rarest female body type is generally considered the hourglass, characterized by shoulders and hips of similar width with a significantly narrower, defined waist, with studies suggesting less than 10% of women naturally fit this description, while some data points to the inverted triangle (broad shoulders, narrow hips/waist) also being quite rare, potentially under 1% in some views, though hourglass is more consistently cited as the least common overall.
By itself, the nabla can be thought of as a vector of partial derivative operators, and when applied to a multivariable function, it represents the vector of partial derivatives of each component (dot product) and the direction of steepest ascent for some input: ∇=[∂∂x∂∂y∂∂z⋮] ∇f(x,y,z,…)=[ ∂∂xf(x,y,z,…) ∂∂yf(x,y,z,…)
In logical argument and mathematical proof, the therefore sign, ∴, is generally used before a logical consequence, such as the conclusion of a syllogism. The symbol consists of three dots placed in an upright triangle and is read therefore.
