\\ \sf\longmapsto AM=(1)/(2)BC


\\ \sf\longmapsto AM=BM=CM

  • All points are equidistant from M

If it becomes a inscribed triangle

  • A,B,C will create a arc of 180°


\\ \sf\longmapsto arcABC=180°

  • The measure of inscribed angle is half the inscribed arc


\\ \sf\longmapsto <BAC=(1)/(2)arc ABC


\\ \sf\longmapsto <BAC=(1)/(2)180°


\\ \sf\longmapsto <BAC=90°

Hence ABC is a right angled triangle (Verified)
