Ray:
* Definition: A ray is a part of a line that has a starting point (endpoint) and extends infinitely in one direction.
* Representation: It's represented by a line with an arrowhead at one end.
Angle:
* Definition: An angle is formed by two rays that share a common endpoint, called the vertex.
* Representation: It's represented by two rays originating from a common point, forming a "V" shape.
Similarities:
* Both involve a starting point: A ray has an endpoint, and an angle has a vertex where the rays meet.
* Both are one-dimensional: They exist within a plane and have length but no width.
Key Differences:
* Direction: A ray extends infinitely in one direction, while an angle is defined by the direction of two rays.
* Measure: A ray doesn't have a measure, while an angle is measured in degrees or radians.
In essence, a ray is a single line segment that extends infinitely in one direction, while an angle is formed by the intersection of two rays.
