Question

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

Answer 1

Which fact is used to prove that angle PTS is always equal to angle RTQ?
Select one:
a. Sum of the measures of angles RTQ and QTS is 180°.
b. Lines PQ and RS intersect at an angle greater than a right angle.
c. Line segments PQ and RS do not have a fixed length.
d. Sum of the measures of angles PTR and QTS is 180°.

Answer 2

Well you can prove the are equal by using the Vertical Angles Theorem.
A step of Vertical Angles Theorem is A, Sum of the measures of angles RTQ and QTS is 180°?

Answer 3

so the answer is A

Answer 4

Yes. You understand it is because of the Vertical Angles Theorem correct?
