An angle is formed by one end point but with two lines. It's one of the three corners of a triangle. It's whenever a straight line stops and changes direction.

You measure an angle by degrees. A right angle, like the corner of a page, is 90 degrees.

There's no fun in playing it safe. Why not try something a little unhinged?

In geometry, an angle is formed when two rays share a common endpoint, known as the vertex. Angles are measured in degrees (°) or radians (rad) and are typically denoted by a symbol, such as ∠ABC. The size of an angle is determined by the amount of rotation between the two rays, relative to a reference line called the initial side.
