Question

Can you form a right triangle form 21, 220, 221

Answer 1

From Pythagorean we know x^2 + y^2 = z^2. (x and y are smaller than z).

Let’s try!

21^2 + 220^2 = 441 + 48400 = 48841.

221^2 = 48841. The same!

So the answer is yes, you can make a right angled triangle.

Answer 2

Yes, 21, 220, 221 can form a right triangle. To determine if a set of three numbers can form a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, we have:

• 21^2 + 220^2 = 48441

• 221^2 = 48841

Since 221^2 is equal to the sum of the squares of 21 and 220, these three numbers form a Pythagorean triple and can form a right triangle..

Hope this helps you
