In the given figure PA and PB are tangents. XY is also a tangent. Prove that:-
i) 2AP= perimeter of triangle PCD.
ii) If, AP=12cm, find the perimeter of triangle PCD.

hi
if 2 tangents are drawn from an external points to a circle , then the tangents are equal in length .
so AC=CE=w , BD=DE=x , PA=PB=y
PC=PA-AC=y-w , PD=PB-BD=y-x
the perimeter of the triangle would be y-w+y-x+w+x=2y
