Solution

The correct options are
A

MC = 5 cm


B

AM = 5 cm


C

MB = 5 cm


In triangle ABC, by applying pythagoras rule,

AC2=AB2+BC2

AC2=82+62=64+36

AC=64+36=100=10 cm

Since, M is the mid-point of AC,

AM=MC=AC2=102=5 cm

We know that in a right angled triangle, mid-point of the hypotenuse is always at equidistance from all the three vertices of the triangle.

AM = MC = MB = 5 cm
