A line is a straight path that goes on forever in both directions. A ray is a straight path that goes on in one direction.
A right angle.
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
Perpendicular line segments are line segments that intersect and make 90 degree angles.
You cannot have a shape without any line segments.
Plain shapes are typically defined by their line segments and angles. A polygon, for instance, is a plain shape consisting of a finite number of line segments (sides) connected end-to-end, forming a closed figure. The number of angles in a polygon corresponds to the number of sides, with each vertex where two sides meet forming an angle. For example, a triangle has three line segments and three angles, while a square has four line segments and four angles.

a pentagon has five sides and five angles
Line
Line segments that have the same length are called congruent line segments, while angles that have the same measure are referred to as congruent angles. Congruence indicates that the two segments or angles are identical in size and shape, though they may not necessarily overlap or be positioned in the same orientation. This concept is fundamental in geometry, particularly in the study of triangles and other shapes.
a line is a ray cause of the angles in directery in the proportion in the radius....
That seems to be true. Sides pretty much are line segments, and the angles are the end points.
