The ancient Egyptians had a neat way to construct right angles. They would make a long rope with knots to make 121212 equal sections. When they stretched the rope into the triangle shown below, they always got a right angle. This was useful when planning the pyramids, for example. If we apply the Pythagorean Theorem to the Egyptian knots we can see that 3^2 + 4^2 = 5^23 2 +4 2 =5 2 3, squared, plus, 4, squared, equals, 5, squared. Which of the sets of three numbers listed would also let you form a right angle in this way? Choose all answers that apply: Choose all answers that apply: (Choice A) A \text{\{36, 85, 77\}}{36, 85, 77}start text, left brace, 36, comma, space, 85, comma, space, 77, right brace, end text (Choice B) B \text{\{24, 24, 30\}}{24, 24, 30}start text, left brace, 24, comma, space, 24, comma, space, 30, right brace, end text (Choice C) C \text{\{2, 5, 9\}}{2, 5, 9}start text, left brace, 2, comma, space, 5, comma, space, 9, right brace, end text (Choice D) D \text{\{5, 12, 13\}}{5, 12, 13}
