Respuesta :

All Sides are congruent is the correct Answer 
PS.Just took the Edgeunity Test 

The missing reason for statement 4 in the given proof is: all sides are congruent.

What are Congruent Sides?

Congruent sides are corresponding sides of corresponding figures that are congruent to each other. This means, they have the same measure of length.

In the proof given, statement 4 states that: AB ≅ BC ≅ CD ≅ DA. This implies equal lengths of sides AB, BC, CD, and DA.

Therefore, the missing reason in the proof is: all sides are congruent.
