Can the triangles be proven CONGRUENT? If so what theorem would you use?

\begin{tabular}{l} 59. Sia \( A B C D \) un rettangolo in cui \( A B=16 \mathrm{~cm} \) e \( B C=8 \mathrm{~cm} \). Siano \( H \) e \( K \), rispettivamente, le proiezioni di \( D \) e \( B \). \\ sulla diagonale \( A C \) del rettangolo. Determina la lunghezza di \( H K \). \\ \hline\( K K=\frac{24 \sqrt{5}}{\mathrm{~cm}} \mathrm{~cm} \)\end{tabular}

A rectangular field is 15 yards in length and 57 feet in width. What is the area of the field in square feet? What is the area of the field in square yards? \( \square \mathrm{ft}^{2} \)

A \( =\{-3,-2,-1,0,1\} \) ve \( B=\{3,4,5,6,7\} \) kümeleri veriliyor. Buna göre \( A \times B \) kümesinin elemanlarını dışarıda bırakmayan en küçük çemberin alanı kaç birim- karedir? A) \( 8 \sqrt{2} \pi \) B) \( 8 \pi \) C) \( 9 \pi \) D) \( 16 \sqrt{2} \pi \) E) \( 16 \pi \)
