Question 1047759: Hi, is there anyway to prove if a line is tangent to a circle without using the radius?
For example, I'm trying to show that DO is a tangent to the circle in red. I know that OAE= AEO= EDG= x, and I don't know where to go from there since I don't know the centre of the circle in red... could you please help me?
Thanks!
