A cool geometry theorem

So today we have a cool geometrical theorem it states a very nice relation between the radius of 2 semi circle and a circle inscribed together very nicely inside a big semi circle . this theorem is absolutely helpful because I have seen many questions in which the radius of the two inscribe semicircle is given and it is asked to find the radius of the complete circle . At that particular point you can solve the question and get the radius but it will take your time , but if you know this particular thing that's very easy to remember you can just give the answer to the next person in just few seconds 😉 If you have any other method other than this you can comment below and if it's hard to comment then you can email me or else you can send it to me on my Instagram or Discord the links are below .
