In a circle that has a radius of one you use Pythagorean theorem to derive the sine, cosine and tangent formulas.
Draw a circle around the origin on graph paper. The sine is the line segment from the point where the side of the angle intersects down to the x-axis. etc.
he discovered it in 196C
To find the length of the third side of a right-angled triangle.
Yes, it's called Pythagoras theorem
Yes. His name is on it.
You can draw it on paper. Not sure what you mean with "working model": this is not about a physical device. Pythagoras' Theorem is about one specific type of calculatoin.
Pythagoras invented the theorem and gave us the relationship between the radius and diameter of a circle to it circumference.
Pythagoras' theorem is applicable to right angle triangles
Most countries recognize the Pythagorean Theorem

TAN on your calculator means TANGENT. In Pythagoras Theorem. Try googling about Pythagoras Theorem and it will answer your questions. Hope this helps.
Yes

Pythagoras's theorem was TT (pi) which is the ratio of the circumference of a circle diameter . The ratio is 3.16 etc and he found that out in the late 19th century.
~The Pythagoras theorem
No. You would have to use Pythagoras's theorem.
Pythagoras invented the Pythagoras Theorem.
