O - the centre of a circle
Rs - two radii
The original question: What is bigger AB or AC?
The answer: Depend on the inequality of the triangle theorem.
My question:
What is the domain of A?
A's size is from what size to what size...

As was pointed out in the immediate previous post,#6, the triangle \(\displaystyle \Delta OBC\) is isosceles meaning that angle \(\displaystyle \angle OBC\) is acute.But Can it will be proven that The max. size of Angle A is 90 degree?
By Synthetic Geometry.
What the meaning of the notion m(angle X)As was pointed out in the immediate previous post,#6, the triangle \(\displaystyle \Delta OBC\) is isosceles meaning that angle \(\displaystyle \angle OBC\) is acute.
Moreover, \(\displaystyle \angle OBC\) is exterior to \(\displaystyle \Delta ABC\) so by the exterior angle theorem \(\displaystyle m(\angle OBC)=m(\angle BCA)+m(\angle BAC)\)
That means that \(\displaystyle m(\angle B{\large\bf{A}}C)<\dfrac{\pi}{2}\)
Because you used the term "synthetic geometry" I naturally assumed that you were literate in the subject.What the meaning of the notion m(angle X)
What is m? ...m(Some Angle) I mean?
