Final answer:
The correct sequence for the proof starts with the distance formula, followed by the definition of congruence, and ends with the property that states if two consecutive sides of a rectangle are congruent, then it is a square.
Step-by-step explanation:
The correct order of reasons that complete the proof for determining whether a rectangle is a square by using the properties of congruence and the distance formula must be logical and sequential. Therefore, the correct sequence is as follows:
Use the distance formula to determine the lengths of the sides of the rectangle.
Apply the definition of congruence to show that the sides are congruent if they have the same length.
Finally, use the property that if two consecutive sides of a rectangle are congruent, then it’s a square.
So the correct order of reasons is distance formula; definition of congruence; if two consecutive sides of a rectangle are congruent, then it’s a square.
