Question

In any triangle abc ab=2 bc=4 ca=3 and d is the mid point of bc then ad^2 is equal to

Answer 1

Step-by-step explanation:

in triangle abc ad bisects it into two equal parts

so in triangle abd

angle adb =90°

and ab =2

as ad divides bc into 2 equal parts so bd=2

now apply Pythagoras theorem

taking ad as perpendicular

ab ad hypotenuse and bd as base

ab^2=√ad^2+bd^2

ad^2= √ab^2-bd^2

solve it and you will get the answer
