Question

plz ans the question now only plzz

Answer 1

10) WE CAN ALSO WRITE
AB = AB+BC
BD = C+CD

AC = BD
AB + BC = BC + CD
(CANCEL BC FROM BOTH SIDE)
AB = CD (HENCE PROVED)

//onother way//
AC = BD
AD-CD = AD-AB
-CD = -AB
AB = CD

9)I THINK YOUR 9TH QP IS WRONG CORRECT IT
BY WRITING " AC = AB/2"

IF
AC = BC
AB-BC = BC
AB = BC+BC
AB = 2BC
AB/2 = BC
AB/2 = AC
