Q What is Line?
What is Point ?
What is Line segment
Answers
Answer:
A line is a one-dimensional figure, which has length but no width.
A point is an exact position or location on a plane surface
a line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
■ Line :- In geometry, the notion of line or straight line was introduced by ancient mathematicians to represent straight objects with negligible width and depth. Lines are an idealization of such objects, which are often described in terms of two points or referred to using a single letter.
■ Line segment :- In geometry, a line segment is a part of a line that is bounded by two distinct end points, and contains every point on the line between its endpoints. A closed line segment includes both endpoints, while an open line segment excludes both endpoints; a half-open line segment includes exactly one of the endpoints.
■ Point :-- In modern mathematics, a point refers usually to an element of some set called a space. More specifically, in Euclidean geometry, a point is a primitive notion upon which the geometry is built, meaning that a point cannot be defined in terms of previously defined objects.
