Hi can anyone help me out with this:
we know
the angle formed by the diameter of the circle at the circumference is 90
but is corollary true?
if angle formed by chord is 90 at the circumference of a circle , is it true that chord will necessarily be diameter?
In case of square or rectangle inscribed in a circle , we take diagonal to pass through centre, by using property 2.plz clear

Yes, you are correct.
If any chord makes a 90 degree angle anywhere in circumference it is a diameter.

Note that the length of the arc and angle subtended at the centre is a one-on-one relation.
Length of arc = Angle/360 * 2*pi*r
So each angle measurement will have a corresponding length of arc. Hence, given either the length of arc or the angle at the centre, we can the find the other uniquely.
Also, angle subtended at the centre is twice the angle subtended at the circumference. Hence, for any given length of arc, the measure of the angle subtended will stay the same and for any given measure of angle subtended, the length of the arc will be the same.
