If u cut that triangle.....direclty in half....along the y axis and/or the imag axis........it is imp for u to realize u have to look at this in diff ways........u would make two right angled triangles............whose hyp is one........and the bottom base is one half........the distance either way to the circle's center................so by the pgy.....t..............1 = a squared + 1/2 squared/.........one squared is still one.....................a squared + 1/4 = 1...................subtract 1/4 from one....it is 3/4.......the square root of which is the square root of 3 over 2...............twice that is the square root of 3.............u have to add another for the rest of the length of the major axis of the ellipse......in the neg y direction or neg imag direction.......................an ellipse whose major axis is the square root of 3 and minor axis is one....has imp. properties.....like a square with sides of 1........the diagonal is the square root of 2.......the square root of 2 added to the square root of 3 is very close to pi......
In mathematics, the Pythagorean theorem, also known as Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Pythagoras' Theorem. Pythagoras. Over 2000 years ago there was an amazing discovery about triangles: When a triangle has a right angle (90°) .
