To Euclid, a postulate is something that is so obvious it may be accepted without proof.
A. A straightedge and compass can be used to create any figure.
That's not Euclid, that's just goofy.
B. A straight line segment can be drawn between any two points.
That's Euclid's first postulate.
C. Any straight line segment can be extended indefinitely.
That's Euclid's second postulate.
D. The angles of a triangle always add up to 180.
That's true, but a theorem not a postulate. Euclid and the Greeks didn't really use degree angle measurements like we do. They didn't really trust them, I think justifiably. Euclid called 180 degrees "two right angles."
Answer: B C

(6)x2 =12
(5)x2 =10
12-10=2
Nine and twenty-seven hundred-thousandths
Both slopes are going to be the same, as parallel lines have the same slopes but different y-intercepts. To find the slope of this line (if you haven’t already), you need to isolate y.
4x - 5y= -1
-5y= -4x - 1 (or -1 - 4x)
-y= (-4/-5)x - 1/5
Canceling out the negatives,
y= (4/5)x + 1/5.
Therefore, the slope of both the listed line and any line parallel to it is 4/5.
