Question

(a) $49 + 40 = 49 + 40$

transltive property of equality
symmetric property of equality
reflexive property of equality

part 2 of 3

(b) if $25 + 20 = 45$, then $45 = 25 + 20$.

transitive property of equality
symmetric property of equality
reflexive property of equality

Explanation:

(a) The reflexive property states that any quantity is equal to itself, which matches $49 + 40 = 49 + 40$.
(b) The symmetric property states that if $a = b$, then $b = a$, which matches the given statement where $25+20=45$ implies $45=25+20$.

Answer:

(a) Reflexive Property of Equality
(b) Symmetric Property of Equality
