Answer:
The symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, <em>AB</em> ≅ <em>CB</em>, then <em>CB</em> ≅ <em>AB</em>.
Step-by-step explanation:
Two triangles are said to be congruent if they have the same three sides and the same three angles, not necessarily the same sides or the same angles are equal.
The properties of congruence are:
For all angles <em>A</em>, ∠A ≅ ∠A. That is, all angles are congruent to themselves.
If <em>AB</em> is side of a triangle then, <em>AB</em> ≅ <em>AB</em>.
For any angles <em>A </em>and <em>B </em>if, ∠A ≅ ∠B, then ∠B ≅ ∠A.
For sides <em>AB</em> and <em>CB</em> of a triangle if, <em>AB</em> ≅ <em>CB</em>, then <em>CB</em> ≅ <em>AB</em>.
For any angles <em>A</em>,<em> B </em>and <em>C if</em>, ∠A ≅ ∠B, and ∠B ≅ ∠C then ∠A ≅ ∠C.
For sides <em>AB, CB </em>and <em>CA </em>of a triangle if, <em>AB</em> ≅ <em>CB</em>, and <em>CB</em> ≅ <em>CA, </em>then <em>AB</em> ≅ <em>CA</em>.
Thus, the symmetric property of congruence is:
If ∠A ≅ ∠B, then ∠B ≅ ∠A.
If, <em>AB</em> ≅ <em>CB</em>, then <em>CB</em> ≅ <em>AB</em>.
