Question

geometry help????? will medal nd fan!!!!!!!!!!

Answer 1

PQ and RS are two lines that intersect at point T, as shown below:

Answer 2

Which fact is used to prove that angle PTS is always equal to angle RTQ?

Sum of the measures of angles RTQ and QTS is 180°.
Lines PQ and RS intersect at an angle greater than a right angle.
Line segments PQ and RS do not have a fixed length.
Sum of the measures of angles PTR and QTS is 180°.

Answer 3

@e.mccormick can you help me?

Answer 4

Well, which of those is always true and has to do with angles? For example, the " Line segments PQ and RS do not have a fixed length." is ALWAYS false because if it is a segment it has a fixed length and even if you talk about lines their infitinte length has nothing to do with angles.

Answer 5

ok

Answer 6

OK? Umm... so which of those is always true and has to do with angles? I already eliminated one. You can eliminate two others.

Answer 7

which one did you eliminate?

Answer 8

For example, the "Line segments PQ and RS do not have a fixed length." is ALWAYS false because if it is a segment it has a fixed length and even if you talk about lines their infitinte length has nothing to do with angles.

The one I said is always false.

Answer 9

could I eliminate Sum of the measures of angles PTR and QTS is 180°.?

Answer 10

Yes. Those would only be 180 at right angles! So that is certainly false.

Answer 11

That leaves only two. One of them is false, the other is the answer.

Answer 12

how about Lines PQ and RS intersect at an angle greater than a right angle?

Answer 13

Yah, that is false and true... it is nonsense. They also intersect at an angle LESS than 90! Just on the other side of the line.

So by killing those three you are only left with one:
Sum of the measures of angles RTQ and QTS is 180°.

Answer 14

ok thank you so much (:

Answer 15

can you help me with another one?

Answer 16

Sometimes multiple choice is about what is right... but with this one is was about what was wrong. =)

Answer 17

ok
