Mystery of the Week: What is the ratio of blue to red area?

The article presents a mathematical puzzle involving two squares drawn within a right-angled isosceles triangle. The goal is to determine the ratio of blue area to red area. The solution explains that by dividing the large triangle into smaller right-angled isosceles triangles, the red square occupies half of the large triangle's area. The blue area is then calculated relative to this, resulting in a final ratio of 8/9 between blue and red areas. The explanation avoids complex calculations by using geometric decomposition.

Bias read (Center): The article discusses a purely mathematical puzzle with no political content or implications. It focuses solely on geometry and problem-solving techniques, making it apolitical in nature.
