Learn the relationship between equal measures and congruent figures. Defn. ∠1 ≅ ∠2 1. Reason: ? Definition: Reflexive Property Definition: Symmetric Property Definition: Transitive Property Definition: Equivalence Relation Example \(\PageIndex{8}\) Congruence Modulo 5 Summary and Review Exercises Note: If we say \(R\) is a Solution: Given statement: If ∠1 ≅ ∠2, then ∠2 ≅ ∠1. The Symmetric Property of Congruence The symmetric property of congruence states that congruence works frontwards and backwards , or in symbols, if then . As long as the congruent angles match up between the triangles (like you learned in Lessons 1 and 2), it does not matter which order you write the triangle name. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. st=qr qr=st a) reflexive property of congruence b) symmetric property of congruence c) transitive property of congruence d) substitution property of congruence of 9 0 ∘ .
