For example, the figure below shows that it starts from point X and point Y is near the arrow end. Ray XY is the segment that runs from point X through point Y and then extends. The name of a ray is given using capital letters; hence, it is denoted as ray $\underset{XY}{\right...

Line线: Is a set of continuous points; it continues on in both directions; and it has no end. Ray射线: Is a line begins at an endpoint; and continues on in one direction without endpoint. Line segment线段: Is a piece of a line between two endpoints. Relationship between two Lines/line...

A line segment represents a collection of points inside the endpoints and it is named by its endpoints.A ray is a line that only has one defined endpoint and one side that extends endlessly away from the endpoint. A ray is named by its endpoint and by another point on the line....
Line Segment – If a line has a starting and an endpoint then it is called a Line Segment. Ray – If a line has a starting point and has no endpoint is called Ray. Eg. Sun Rays Angles in Geometry In planar geometry, an angle is the figure formed by two rays, called the sides of...
A line segment is a part of a line having two endpoints. The length of this line segment will be denoted as AB. Ray A rayis a part of the line segment that has only one endpoint. The above ray will be read as ray CD. It is important to note here that the endpoint of the ray...
Line segment: A line segment has two end points with a definite length. Ray: A ray has one end point and infinitely extends in one direction. Straight line: A straight line has neither starting nor end point and is of infinite length. ...
The second type of line is called aray, and these go on forever. They are often drawn as a line starting from a point with an arrow on the other end: Parallel and perpendicular lines There are two types of lines that are particularly interesting and/or useful in mathematics.Parallel lines...
A line does not have any endpoints. A ray has only one fixed point. A line segment is a part of a line that has a fixed length. Perpendicular lines have a 90-degree angle between them. Parallel lines do not meet. Solved Examples Example 1 Sam wants to find out the figures which ...
