Pythagoras theorem will always work with a right-angled triangle.
no
No it never works.
work
it is a modified version of one of the newtons equation , newton equation cannot define the relation between work and enrgy thats why we generate the relation for work enrgy theorem
Brahmagupta worked with Pythogoras.
yes
You cannot.
You don't, unless you work in engineering. The Wikipedia article on "binomial theorem" has a section on "Applications".
