What is the meaning of this statement:" ..the angle between the lines joining the focus to the minor axis is 90Â°"?
Is 90 degree the angle between the lines joining one of the focus to the two ends of the minor axis, or is it the angle between the lines joining the two foci with one end of the minor axis?

I think it should be the angle between the lines joining the two foci with one end of the minor axis

if it is the end ,.........

b = ae

b^2 = a^2 - b^2

b = a/root2 = 1!!!!!!
