What is an angle?

What is an angle?

Four separate labelled angles showing acute 35°, right 90°, obtuse 120°, and reflex 250°

An angle measures the turn between two straight lines that meet at a point. The point where they meet is called the vertex, and angles are measured in degrees, written with the symbol ∘^\circ∘.
