Question

The figure below shows a rectangle ABCD having diagonals AC and DB.
Anastasia wrote the following proof to show that the diagonals of rectangle ABCD are congruent.
Anastasia’s proof
Statement 1: In right triangle ADC, the sum of the squares of sides AD and DC is equal to the square of hypotenuse AC so that AD2 + DC2 = AC2 and in right triangle ABD, the sum of the square of sides AD and AB is equal to the square of hypotenuse DB so that AD2 + AB2 = DB2 (by symmetric property of equality)
Statement 2: AB = DC (opposite sides of a rectangle are congruent)
Statement 3: AC2 = DB2 (from state
