Answer this question

Answer 1

(i) AB² +AC² = BC²

   [according to Pythagoras theorem hypotenuse²= base²+altitude² ]

Answer 2

First find the third angle.           Angle a =180-angle(b+c).  Angle a =90.      The use pythagorus theorem. In this case (ab)^2+(ac)^2 =( bc)^2. So both a and b are correct
