1. To construct a square, we need to know:
a) All the interior angles
b) All the side lengths
c) Only one interior angle
d) Only one side length

Explanation: A square has all its sides equal and all the interior angles measure 90 degrees. Hence, if the length of one side is known, then we can construct a square easily.
