Which set represents a Pythagorean triple?
A.1,2,4
B.2,4,6
C.3,4,10
D.5,12,13
Is the answer C?
I asked Brady for help. Why are you getting involved. This is a site to help me at least he was showing me how to get the right answer.
No. Please use a^2 + b^2 = c^2 to find the correct answer to this problem. Please see the other posts for these type of problems.
Nobody explains it the way you do. I'm in 8th grade and this is really hard on me, then she comes in and ruins the help i am getting. I need you.
Brady I like it when you help me. She is always picking on me for not knowing the answer. You help me by showing me how to get the answer. Please stay with me. Don't leave me please. I wait everyday to hear from you.
She is not "picking" on you. However, if you haven't tried the way that many people have explained to you, you do need to. It will help you a lot more, and it will get easier for you. I am in 9th grade, and I have never done these type of questions before. However, I get everything completely with these because of "algebra".
To determine whether a set represents a Pythagorean triple, we need to check if the three numbers satisfy the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's apply the theorem to each set:
A. 1, 2, 4 => 1^2 + 2^2 = 1 + 4 = 5 ≠ 4^2 (not a Pythagorean triple)
B. 2, 4, 6 => 2^2 + 4^2 = 4 + 16 = 20 ≠ 6^2 (not a Pythagorean triple)
C. 3, 4, 10 => 3^2 + 4^2 = 9 + 16 = 25 = 5^2 (not a Pythagorean triple)
D. 5, 12, 13 => 5^2 + 12^2 = 25 + 144 = 169 = 13^2 (a Pythagorean triple)
Therefore, the correct answer is D. 5, 12, 13.
It looks like we tutors have failed.
We've tried and tried to teach you about Pythagorean Triples. Apparently we haven't succeeded.
Please go back and reread all of the answers and website we've posted for you.
