Substitution Property

Practice makes perfect

To identify the Property of Equality being demonstrated by the given equations, we should first identify the operation being performed.

Ifm∠ 1+m∠ 2=90 andm∠ 2=m∠ 3, thenm∠ 1+m∠ 3=90. In this case, we are given three equations. m∠ 1+ m∠ 2= 90 m∠ 2= m∠ 3 ⇓ m∠ 1+ m∠ 3= 90 This demonstrates the Substitution Property.
