Angle — 0° (Zero Angle) — free printable diagram

What is a 0 degree angle?

A 0 degree angle (0°) is a zero angle — the two arms lie exactly on top of each other, so there is no opening between them. This diagram shows the two arms closed together at the vertex, with no gap between them.

• A 0° angle is a zero angle because the two arms lie exactly on top of each other, so there is no opening between them.
• In radians, 0° × π/180 = 0.
