(HKDSE Math) HKMCPSC Inscribed circle problem | 香港中學數學創意解難比賽內接圓問題 (Cantonese)

This question is adapted from 2017-2018 Hong Kong Mathematics Creative Problem Solving Competition. It involves the calculation of the radius of the circle inscribed inside the figure. I provided another solution apart from the suggested one. The skills needed are also necessary for HKDSE Math (Comp). Enjoy~ 這條題目來至2017-2018香港中學數學創意解難比賽，涉及計算圖中內接圓形的半徑。我提供了另一解題方法，而當中的技巧亦適合文憑數學考試 *************************************************** Thank you very much for your watching and support! 謝謝各位的觀看和支持!
