- No, because if the points were FEA, it would be an angle, specifically an obtuse angle.
- I think that if you just had one point then you couldn't know what direction the ray was going. like the sun is the end point but it puts out rays...
- Geometry is the mathematical study of shapes, yes. All math deals with logical reasoning, though it is typically first taught in a formal way in Ge...
- It is a line, but the connected points that make up the line could also result in rays, since a ray only requires a start point and another to spec...
- They are the same ray if they start on the same point and go the same direction.
- He is using a slash symbol in a grammatical rather than a mathematical sense, to say that ray CF and ray CE are the same ray. He could have also wr...
- The arrow over the top is a symbol, and doesn't really indicate which way the ray is headed. This could get tricky if the ray was pointing straight...

Jan 11, 2023 · How to draw a ray; Symbol and Label; Examples; Ray definition in geometry. A ray is part of a line. Rays have a fixed starting point and no end point. A ray extends in only one direction infinitely. The ray's starting point and another point along the ray are used to name the ray in geometry.
