In the figure AC is the diameter of circle, with centre O, chord BD is perpendicular to AC.
Write down the angles p, q, r in terms of .
q = , r = 90 + , p = 90 –
q = 2, r = p = 90 + /2
q = /4, r = p = 180 – /2
q = , r = p = /2
q = /2, r = p = 90 – /2
In the given figure, AC is the diameter of circle, centre O. Chord BD is perpendicular to AC. Write down the angles p,q and r in terms of x.
