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.

In ordinary geometry, no. Any ray will have infinitely many points.
with an arrow on the top of two letters. like you have an AB ray so you rite --> on top
Euclid of Alexandria (325-265 BC) was one of the greatest of all the Greek geometers and is considered by many to be the "father of modern geometry"

A ray
Because we can't see the image you're referring to, we can't give the answer to which ray is opposite to BA. However, we can help. Opposite rays are two rays that both start from a common point and go off in exactly opposite directions. So, if there are two rays (BA and BC) with a common endpoint (B) going in different directions, they are called opposite rays.

300 bc by euclid a greek mathmatician.
The formal study of geometry has been attributed to Euclid, who lived in Alexandria about 300 BC.
The first recorded study of spherical geometry was by Autolycus of Pitane, in the 4th century BC.
The ray opposite from ray BA is ray AB. These rays form a straight line.
In ordinary geometry, no. Any ray will have infinitely many points.
rays BE and BC
An opposite ray is a pair of rays that share the same endpoint and extend in opposite directions. This can be visualized as two rays emanating from a common point but extending in opposite directions along the same line.
