No, they are different!
yes
yes they are same.
Yes, line segments CD and dc are considered the same because they represent the same line segment regardless of the order of the endpoints. In geometry, the notation for a line segment does not depend on the sequence of the letters; both CD and dc denote the same path between points C and D.
No, ray CD and ray DC are not the same. A ray is defined by its starting point and extends infinitely in one direction. Ray CD starts at point C and extends through point D, while ray DC starts at point D and extends through point C, thereby having different directions.
If you mean CD plus DC then in Roman numerals they add up to M meaning 400 plus 600 = 1000
No. Line CD is the same as line DC, but rays are always named from the origin point, so ray DC is a ray pointing in the opposite direction from ray CD.

Ab and Ba are the same line because there are no endpoints to a line. Therefore, you can reverse the order of the letters. So, Cd and Dc are not the same ray because the first letter is the endpoint. So on ray Cd, point C is the endpoint and d is a point on the line coming from the endpoint. On ray Dc, D is the endpoint.
They define the same line segment, connecting two points.
