7. In OD, is the diameter of the circle and ZX WY. What conclusions can you make? Justify your answer

Solution

We know that a chord to a circle passing throught the center is essentially the diameter. If it is perpendicular to some other chord then it bisects the other chord.

The exacct same circumstances here:

ZX is perpendicular to WY

and D is the center through which ZX passed. hence, ZX divides WY into 2 parts. Let the point of intersection be T

So, WT = TY <-- this is the conclusion
