## Susan9419 3 years ago PLZ HELP!! Which of the following statements is NOT a good definition? An angle bisector is a ray that divides an angle into two congruent angles. Two lines are parallel if and only if they are coplanar and do not intersect. A segment is a part of a line. An angle is a right angle if it measures exactly 90 degrees.

Well, we know that d is correct because a right angle is 90 degrees...

2. kewlgeek555

I think b sould also be correct. So that leaves us w/ a and c

3. JakeV8

all these are sort of right :) I think the key is the phrase "good definition"

4. Susan9419

ok, so whatt do u think it would b?

5. kewlgeek555

I dont know what grade you are in but I dont what an angle bsector is so...

6. Susan9419

i think its a is that correct?

7. miteshchvm

i guess d is the answer, bcz right angle can be defined as the angle formed by two perpendicular lines that intersect.

8. JakeV8

I think a is not the answer... a is a decent definition for an angle bisector.

10. Susan9419

so if a is not the answer and c is not the answer what is??

11. miteshchvm

the answer is "D" see my comment above!

12. JakeV8

You are saying that D is not a good definition of a right angle?

13. Susan9419

so it would be b?

14. JakeV8

This question is poor, but my vote is for (C) A segment does not HAVE to be part of a line.. .it can be a lonely segment all alone, no line to belong to :)

ok thats good enought for me thank you so much!!
