Does 32, 57, 65 form a right triangle?

Nope.

A right angle triangle is form only when one given angle is 90 degree.

:)) ur welcome

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
