Answer :

A good way to look at this is the words themselves. The first hexagon is "equiangular," and the second is "equilateral." The word "equiangular" has a variation of the word "angle" in it, so an equiangular hexagon has congruent angles. equilateral means congruent sides, and a good way to remember this is Lateral => Line, and sides are lines.
Final answer:
equiangular hexagon has congruent angles, equilateral hexagon has congruent sides.
