The question is...
"Cristiano Ronaldo is jealous of Paul Pogba's dab, so Pogba tries to demonstrate that his is perfect. According to the book 'the Universal Declaration of the Rights of the Dab', a dab is only perfect if the triangles represented in the figure below are right-angles.
Is Paul Pogba's dab perfect?"
Hmmm...that's a hard one
Pogba's dabs are ALWAYS perfect!
