Prove that line joining the mid point of hypotenuse of right angled triangle to opposite vertex is half the hypotenuse.

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,
