Triangle symbols are Unicode triangles and arrowheads pointing in every direction: filled and hollow upward and downward triangles (▲ △ ▼ ▽), left- and right-pointing ones (◀ ◁ ▶ ▷), the small arrowheads (◄ ►), and corner triangles (◤ ◥ ◣ ◢). They double as directional markers and decoration. The right-pointing ▶ is the universal play button; ▲ ▼ work as up/down or expand/collapse indicators; and ◀ ▶ act as previous/next cues. People paste them into bios and captions as sharp bullets, use ▲ △ in minimalist and geometric aesthetic profiles, and drop ▶ before a link to mimic a play prompt. The corner triangles (◤ ◥) build angular frames and simple shapes. Unlike round or square sets, triangle symbols carry a built-in sense of direction and motion, making them equally at home as functional cues and edgy decoration.
Triangle Symbols to Copy
Directional shapes and what they signal
Triangles read as pointers, so each direction implies an action. ▶ is recognized almost everywhere as play, and ◀ as back or previous; ▲ and ▼ suggest up and down, increase and decrease, or expand and collapse in menus. Filled versions (▲ ▼ ◀ ▶) look bold and button-like, while hollow ones (△ ▽ ◁ ▷) feel lighter and more decorative. The corner triangles (◤ ◥ ◣ ◢) fill one corner of a square, which is why they're used to build angular frames. Most come from the Geometric Shapes block and are widely supported, so their directional meaning comes through clearly.
Play buttons, menus, and geometric decor
Drop ▶ before a link or video mention to nudge a tap (▶ Watch now), and use ◀ ▶ as previous/next markers in a caption carousel. In a bio, ▲ can flag a highlight and ▼ point down to a link in the next line. Minimalist and vaporwave profiles use bare △ ▽ as clean accents around a name. The corner triangles let you sketch simple angular borders, like ◤━━◥ across a header. As bullets, ▸ or ▹ give a sharper look than a dot. Keep functional triangles like ▶ unambiguous by leaving them near the text they point to.
Frequently Asked Questions
Which triangle is the play button symbol?▼
The right-pointing filled triangle ▶ is the one universally read as play. Its hollow version ▷ and the smaller arrowhead ► look similar and also suggest play or next. Pair it with text like ▶ Watch to make the cue obvious, since on its own a triangle can also be interpreted simply as a direction marker.
What are the corner triangles ◤ ◥ ◣ ◢ for?▼
These fill just one corner of a square, so people use them to build angular frames, banners, and simple geometric shapes in text art. Placed together they can form larger triangles or decorative borders around a name or header. They carry no directional meaning like the arrow triangles; they're purely for shape-building.
What's the difference between filled and hollow triangles?▼
Filled triangles (▲ ▼ ◀ ▶) look bold and button-like, which suits play buttons, menu toggles, and strong markers. Hollow triangles (△ ▽ ◁ ▷) are lighter and read as decorative, so they fit minimalist and aesthetic profiles better. They point the same directions; the choice is about how much visual weight you want.
