Hi how are you doing today Jasmine
The best answer I can think of is that a line doesn't have a point where it starts or stops, but instead goes on forever, unlike a ray which has a start or end point but not the other, and a line segment which has a start and stop point. Hope this helps!
Answer:
They are congruent.
Step-by-step explanation:
We know this for the fact that angle D and angle A are the same.
Angle B and angle A are the same
The line AB and DE are the same.
Not sure about transformations but I think it was transformed around the origin.
Not 100 percent about the last part.
Hope this helps.
I'm pretty sure that it is 90.
