In a right angled triangle ∆ DEF, if the length of the hypotenuse EF is 12 cm, then the length of the median DX is

1. 3 cm.
2. 4 cm.
3. 6 cm.
4. 12 cm.

Correct Option: C

As per the given in question , we draw a figure of right-angled triangle FDE

ED The median splits the right triangle into two isosceles triangles and the median is half the length of the hypotenuse.
∴ EF = 12 cm.
⇒ DX = XE = XF = 6 cm.
