Answer:
c) 1.2 mm, 1.6 mm, 2 mm
Step-by-step explanation:
In order to find which sides equal a right triangle, you need to use the Pythagorean Theorem: 
Set up the equation with the first numbers. The two shorter sides (legs) are A and B, and the longest side (hypotenuse) is C.
= 

Since the two sides are not equal, the first option is not a right triangle.
When you follow these steps with the remaining three options, you'll find that the third option (C) makes a right triangle.
