Final answer:
Without additional context, it is unclear what actions of 'Hexagon' made 'Sphere' angry as the question appears to be about personified shapes in a storytelling context, possibly used to teach mathematical concepts in an engaging way.
Step-by-step explanation:
The question "What did Hexagon do that made Sphere angry?" appears to be part of a mathematics context, specifically geometry, where shapes are personified to help explain concepts.
However, without specific context, it is impossible to provide an answer in 200 words that would be accurate. Instead, this question seems to be more akin to an English or storytelling exercise, where anthropomorphic figures are used to create a narrative that can make mathematical concepts more accessible and engaging to students.
If there is a specific story or lesson that this question is referring to, please provide additional details so that a factually accurate response can be given. It is important in these types of exercises to blend educational content with creative storytelling to facilitate learning.
