Name all points collinear with E & F
OpenStudy (helder_edwin):
collinear means they are over the same line
OpenStudy (anonymous):
Collinear means points lie on the same line not over
OpenStudy (helder_edwin):
sorry that's what i meant

yeah the first one is line and the other one is line segment
OpenStudy (anonymous):
wait is that right?
OpenStudy (helder_edwin):
the other way around
OpenStudy (anonymous):
yeah okay lol
OpenStudy (helder_edwin):
just checking. this diffence gives u the answer B to (f).

oh really didnt know that? well (g)
OpenStudy (helder_edwin):
the \(\cap\) means intersection. i.e., what is common to both segments!!!
OpenStudy (anonymous):
G?
OpenStudy (helder_edwin):
yes. now (h)
the \(\cup\) means "union". i.e., put the segments together!!
OpenStudy (anonymous):
AGF?

OpenStudy (helder_edwin):
no. it has to be a segment!!!
OpenStudy (anonymous):
OH okay my baaad. umm idk because im looking at it and i have an answer but it might be wrong
OpenStudy (helder_edwin):
u r learning.
making mistakes here costs u nothing.
making mistakes in your tests will cost dearly

again. i can't read it completely.
OpenStudy (anonymous):
there is only one way to list it...
OpenStudy (anonymous):
B lies on a ray whose endpoints is E. Name this ray in all possible ways.
OpenStudy (helder_edwin):
u have 3 possible ways. which are they??
OpenStudy (anonymous):
umm DBE,EBD, and umm thats all i can see

OpenStudy (helder_edwin):
no. to denote a ray is quite same as for a segment: two points.
OpenStudy (anonymous):
ohh okay umm lemme try again
