The proof shows that ABCD is a rectangle. Which of the following is the missing reason?
patriot [66]

Answer:

Side-side-side postulate

Step-by-step explanation:

In the first statement, we are given that AC = BD ....... (1){It is given}

Now, in the second statement, we are given that AB = DC ...... (2){ Because the parallelogram has equal opposite sides}

Now, again we are given that AD = DA ........... (3) {From the symmetric property}

Now, conditions (1), (2), and (3) are applicable to say that Δ ABD and Δ ACD are congruent.

Since there are three sides involved to say Δ ABD ≅ Δ ACD, so it is by Side-side-side postulate. (Answer)

german

Answer:

11.7 cm

Step-by-step explanation:

Using Pythagoras Theorem

AC² = AB² + BC²

AB = 4 cm

BC = 11 cm

AC² = 4² + 11²

AC = √4² + 11²

AC =✓137

AC = 11.704699911 cm

Approximately = 11.7 cm

Length AC = 11.7cm
