Although I cannot locate the video I shared with my students about the angle theory associated with the shape of Hindu-Arabic numerals, I found this one that is similar:
Were Numbers Created from Angles? A Geometric Perspective

Description:
Were numbers really created from angles? One fascinating theory suggests that early numerals were designed based on the number of angles in their shape!
This idea proposes that each digit from 1 to 9 was originally formed using a specific number of sharp angles, offering a geometric explanation for numeral design. But is there any truth to this? π€
In this video, we explore the ‘Angles Theory’ of Numbers and how each digit might have been shaped based on angles alone.

While this theory presents an interesting perspective, it’s important to note that the numerals we use todayβ0 to 9βcome from the Hindu-Arabic numeral system, which originated in India and was later refined by Arabic scholars before spreading worldwide. However, the ‘Angles Theory’ remains a fun and creative way to rethink how numbers might have been designed!
