Answer 1

The figure below shows a rectangle ABCD having diagonals AC and DB:

A rectangle ABCD is shown with diagonals AC and BD.

Anastasia wrote the following proof to show that the diagonals of rectangle ABCD are congruent:

Anastasia's proof:
Statement 1:
Statement 2: AB = DC (opposite sides of a rectangle are congruent)
Statement 3: AC2 = DB2 (from statements 1 and 2)
Statement 4: AC = DB (taking square root on both sides of AC2 = DB2)

Which statement below completes Anastasia's proof?

In triangle ADC and BCD, AB = DC (opposite sides of a rectangle are congruent)
In triangle ADC and BCD, AB = DC (opposite sides of a rectangle are parallel)
In triangle ADC and BCD, AD = BC (opposite sides of a rectangle are congruent)
In triangle ADC and BCD, AD = BC (opposite sides of a rectangle are parallel)

Answer 3

I am thinking A or B

Answer 4

@NatalieF I need help please and thank you

Answer 5

I think ' In triangle ADC and BCD, AD = BC (opposite sides of a rectangle are congruent) '

Answer 6

A and B should be eliminated because In triangle ADC and BCD , the line AB does not appear in triangle ADC
