[Answer] A theorem on right triangles is named after which Greek philosopher?

Step 1 : Introduction to the question "A theorem on right triangles is named after which Greek philosopher?"

...The Pythagorean Theorem is named after Pythagoras, a Greek philosopher and mathematician who lived around the 6th century BCE. The theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides (a² + b² = c²). While versions of this mathematical relationship were known to earlier civilizations, Pythagoras and his followers are traditionally credited with formally systematizing and proving it, making it one of the most fundamental and enduring principles in geometry.

Step 1 : Introduction to the question "Which U.S. river is widely known for flowing backward?"

...The Chicago River is renowned for flowing “backwards” after a landmark engineering project completed in 1900 reversed its natural direction. Originally draining into Lake Michigan, the river was redirected away from the lake through the Chicago Sanitary and Ship Canal to protect the city’s drinking water from sewage contamination.
