Question

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.

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

ok, so whatt do u think it would b?

Answer 5

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

Answer 6

i think its a is that correct?

Answer 7

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

Answer 8

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

Answer 9

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

Answer 10

the answer is "D" see my comment above!

Answer 11

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

Answer 12

so it would be b?

Answer 13

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 :)

Answer 14

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