\( \mathrm{AA}^{\prime} \) and \( \mathrm{BB}^{\prime} \) are two direct common tangents to two circles intersecting in the points \( \mathrm{P} \) and \( \mathrm{Q} \). The common chord when produced intersect \( \mathrm{AA}^{\prime} \) at \( \mathrm{M} \) - and \( \mathrm{BB}^{\prime} \) at \( \mathrm{N} \), then \( \mathrm{AA}^{12}+\mathrm{PQ}^{2} \) is equal tohttps://bit.ly/YTAI_PWAP https://www.pw.live
