is △YXZ ≅△AZX additon property

No, the addition property does not apply to triangles. The addition property states that if a=b, then a+c=b+c. This property is used for adding or subtracting the same value to both sides of an equation or inequality.

However, in this case, we are comparing the congruence of two triangles. The notation △YXZ ≅△AZX indicates that triangle YXZ is congruent to triangle AZX. Congruence of triangles is determined by specific criteria such as equal sides and equal angles, but not through addition or subtraction.
