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)

Question 1 options:
1) The sum of the measures of angles RTQ and QTS is equal to the sum of the measures of angles QTS and PTS.
2) Angle RTQ and angle QTS are complementary angles.
3) The sum of the measures of angles RTQ and PTS is equal to the sum of the measures of angles RTP and QTS.
4) Angle RTQ and angle PTS are supplementary angles.

Answer 1

If you take a closer glance, are the angles complementary or supplementary? I think the answer is #2.

Answer 2

Wait, #4.

Answer 3

4? Thank you @annaliesebronz
