Who said there no royal way to learn geometry?

The quote "There is no royal road to geometry" is often attributed to Euclid, the ancient Greek mathematician.

While there is no definitive proof that Euclid actually said this, it has been passed down through history and is associated with his rigorous approach to geometry, emphasizing logic and proof. This quote reflects the idea that learning geometry requires dedication, effort, and a willingness to engage with the material.
