It is a line segment.
a fixed pulley is a pulley attached to a support.
They are points whose positions do not change under transformations.
I believe that is the definition of a straight line.
An axis.
FIxed reference points refers to a coordinate system or set of axes within which measure the position, orientation and other properties of an object in the drawing.
There do not appear to be ANY "fixed points" in the Universe. Everything is in motion, and there is no "preferred" frame of reference.
Reference points are used to determine motion by comparing the position of an object relative to those points over time. If the object changes its position relative to the reference points, then motion has occurred. By observing the changes in the object's position relative to fixed points, we can determine its motion, speed, and direction.
Stationary reference points are chosen to determine motion because they provide a consistent and fixed frame of reference. By using stationary reference points, it is easier to identify when an object is moving relative to its surroundings. This helps in accurately measuring the speed and direction of the object's motion.
It is because all measurements are taken from that point: it is the fixed point of reference.
A fixed point is a reference point that remains constant during movement, allowing us to determine the direction and distance of the movement relative to that point. By using fixed points as landmarks or reference markers, we can navigate and track the changes in position accurately.
A fixed location in space is a point in the three-dimensional coordinate system that remains constant and does not change its position relative to other points. It serves as a reference or anchor point for measuring distances and positions within a specific frame of reference.
Two nonmoving objects that are useful reference points are a stationary pole or a fixed building. These objects can serve as points of comparison or markers to determine direction, distance, or positioning.

A frame of reference in physics, may refer to a coordinate system or set of axes
Geographic North Pole Fixed stars in the night sky Earth's equator
A reference point is an object or point from which movement is determined. It serves as a fixed location or frame of reference that helps to describe the motion of other objects or points in relation to it.
