It depends if this definition is the same as what you consider and angle.
In geometry, an angle (in full, plane angle) is the figure formed by two rays sharing a common endpoint, called the vertex of the angle. The magnitude of the angle is the "amount of rotation" that separates the two rays, and can be measured by considering the length of circular arc swept out when one ray is rotated about the vertex to coincide with the other (see "Measuring angles", below). Where there is no possibility of confusion, the term "angle" is used interchangeably for both the geometric configuration itself and for its angular magnitude (which is simply a numerical quantity).
What else can I help you with?
What is the unit measured by a protractor?
A protractor measures the angle between two lines meeting at a point called a vertex. The angle measurement is in degrees.
In geometry an angle is formed by what?
If you mean an angle then an angle is formed by two straight lines meeting at a vertex.
What is the v-shaped meeting point of two lines?
An angle
What does a vertex form?
a meeting point of two lines that form an angle; a corner.
What kind of line is x?
It is not a line. X is two lines meeting in a perpendicular angle(right angle)(90 degrees).
