# Is it a Right Triangle?
# Write a program which judges wheather given length of three side form a right triangle. Print "YES" if the given sides (integers) form a right triangle, "NO" if not so.
#
# Input
# Input consists of several data sets. In the first line, the number of data set, N is given. Then, N lines follow, each line corresponds to a data set. A data set consists of three integers separated by a single space.
#
# Constraints
# 1 ??? length of the side ??? 1,000
# N ??? 1,000
# Output
# For each data set, print "YES" or "NO".
#
# Sample Input
# 3
# 4 3 5
# 4 3 6
# 8 8 8
# Output for the Sample Input
# YES
# NO
# NO
