Question

please help// geometry question

Answer 1

a.   Since a line doesn't have endpoint, it doesn't matter which

two points we use to name a line so we could call this line DC.

b.   A ray is a figure that starts at and endpoint and continues

forever in one single direction. So a ray here would be ray AB.

c.   Opposite rays are two rays that share a common endpoint,

have no other points of intersection, and all points are collinear.

So ray EC and ray ED would be opposite rays.

Answer 2

A) Line names are made using two letters, since line CD passes through E, line CD could be renamed CE

B) a Ray has one end point and goes in one direction. If A is the endpoint, the line goes through point B

The Ray would be AB with an arrow pointing to the right above the letters.

C) Opposite rays create a straight line and have the same point.

Ray ED is opposite EC
