What is a value that can be used as a reference point?
A Benchmark Fraction.If Zero is the description of nothing then it would be a useful reference point as everything else can be clearly defined
What is used to compare two numbers on a graph?
Their position relative to a reference point - often the origin.
Why do we always start at the origin point?
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
What is the angular distance around the horizon from some reference point?
If the reference point and an object are both on the horizon then the angular distance to the object, relative to the reference point is simply the angle formed between the two rays from the observer to object and to the reference point. If either the object or reference point (or both) are not in the plane of the horizon then the appropriate rays are the projections of the rays from the observer onto the plane containing the horizon.
