Answer:
A.
Step-by-step explanation:
We are given that two lines PQ and RS are intersect at point T.
We have to find the fact which is used to prove that angle PTS is always equal to angle RTQ.
We know that linear angles are supplementary and sum is 180 degrees
Therefore,
From both equation we get
Cancel angle QTS on both sided the we get
Hence, option A is true.
Therefore, when two lines are intersect then opposite angles are equal.
