Question

PQ and RS are two lines that intersect at point T.


Which fact is used to prove that angle PTS is always equal to angle RTQ? (1 point)


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 1

can anyone help me?

Answer 2

It's the first choice...they're supplementary angles :D

Answer 3

can you help me with a couple more?

Answer 4

Actually it is Vertically opposite angles.. but no option available

Answer 5

so is it the first one?

Answer 6

That's RTQ and QTS are supplementary...sorry for the confusion

Answer 7

so what would the answer be?

Answer 8

I'm pretty sure it's the first choice

Answer 9

ok cool can you help me with another?

Answer 10

Maria drew two parallel lines KL and MN intersected by a transversal PQ, as shown below.


Which fact would help Maria prove that the measure of angle KRQ is equal to the measure of angle MSQ? (1 point)


Alternate interior angles KRS and RSN are equal, and consecutive angles KRS and KRP are complementary.
Alternate interior angles LRS and RSN are equal, and vertical angles RSN and MSQ are supplementary.
Vertical angles MSQ and RSN are equal, and alternate interior angles KRS and RSN are equal.
Vertical angles LRS and KRP are equal, and consecutive interior angles PRL and LRS are equal.

Answer 11

yes.. first one

Answer 12

Do it in a new question though

Answer 13

ok this is the next question

Answer 14

alright ill tag you guys
