2. substitution property of equality

Answer 2

Answer:

1. Linear pair postulate

2. Substitution property of equality

Step-by-step explanation:

We are given that QS is a line segment and m∠QRT= 110°,we have to prove that m∠TRS=70°.

Since, QS is a line segment which is given⇒∠QRT and ∠TRS are the linear pair of angles by the property of linear pair angles⇒∠QRT and ∠TRS are the supplementary angles by the linear pair postulate⇒m∠QRT+m∠TRS=180° by the dfiition of the supplementary angles⇒By substituting m∠QRT=110° in this, by using the substitution property of equality, then we have m∠TRS=70° by subtraction property of equality.
