Question 926196: Two circles C1 and C2 touch each other internally at P. Two lines PCA and PDP meet the circles C1 in C,D and C2 in A,B respectively. if angle BDC = 120, then the value of angle ABP is equal to Answer by Edwin McCravy(20060) (Show Source):
You have a typo because "line PDP" has two P's in it,
and it's supposed to meet C2 in A and B. That means
what you're calling line PDP also has the points A and
B on it. Please correct the typo in the thank-you
note form below and I'll get back to you. Sorry.
