geometrya straight, one-dimensional figure that extends infinitely in both directions.
A line is a straight, one-dimensional figure that extends infinitely in both directions.
A point in geometry is a specific location in space, represented by coordinates in a given coordinate system. It has no dimensions, only position. In a two-dimensional space, a point is represented by an ordered pair of numbers (x, y).
A ray starts at a point, called the endpoint, and extends infinitely in one direction.
An angle is the figure formed by two rays sharing a common endpoint called the vertex. Its size, measured in degrees or radians, is the amount of rotation needed to align one ray with the other.
In geometry, two lines or planes are said to be perpendicular if they intersect at a right angle (90 degrees).
