Answer
$11^2 + 60^2 = 61^2$
they are equal to each other
Work Step by Step
a right angle will always follow this kind of converse $a^2 + b ^2 = c ^2 $
When we plug in the values the biggest value will be C and the 2 smaller values will go in a & b
in this case $11^2 +60^2 = 3721
$
121 + 3600 = 3721
