How much of the description is necessary in order to find the solution?
"If an equilateral triangle and three isosceles triangles together make a rhombus, what must the angles in the rhombus be?"
Do we really need to know that it's a rhombus?
Could we just be told it's a parallelogram?

How common are self-scanning scams? If anonymous online questionnaires are any indication, very common. When Voucher Codes Pro, a company that offers coupons to internet shoppers, surveyed 2,634 people, nearly 20 percent admitted to having stolen at the self-checkout in the past. More than half of those people said they gamed the system because detection by store security was unlikely. A 2015 study of self-checkouts with handheld scanners, conducted by criminologists at the University of Leicester, also found evidence of widespread theft. After auditing 1 million self-checkout transactions over the course of a year, totaling $21 million in sales, they found that nearly $850,000 worth of goods left the store without being scanned and paid for.
