Answer» Given : In right angled ΔABC ∠ABC = 90° and point M is mid point of hypotenuse AC To Prove : BM = AM = CM Construction : Taking AC as a diameter draw a circle which passes through B. Proof : Hypotenuse AC diameter circle, of right ΔABC, AC is M is mid point of AC so M will be center of circle Thus, AM = MC …(i) [M is mid point] BM = MC ….(ii) [Radius of circle] From equations (i) and (ii) BM = AM = MC = \(\frac { 1 }{ 2 }\)AC, |
