Crime 2: Some thief has taken a necklace from old Mrs. Hexagon. The culprit ran off very fast, but not before some bystanders got a look at the culprit.

Mrs. Hexagon -- "It all happened so fast! All I can tell you is that the thief had congruent diagonals."

Little Boy Square -- "As this individual was fleeing the scene of the crime, I saw a pair of parallel sides. I did not get a look at the other pair of sides, so I'm not sure if there were two pairs or not."

Lunch Lady Heptagon -- "I did not notice if the sides were parallel or not, but I saw a pair of opposite sides that were definitely not congruent."

Crime 3: Someone used spray paint to put graffiti on the wall outside the shape shack, a local burger joint for polygons. While there were not many people there at the time, there were a few witnesses who were able to help with the investigation.

Skinny Rectangle -- "All I can tell you is that shape I saw leaving had two pairs of congruent sides."
