In the figure below, if AC>AB and D is point on AC such that AB = AD, then the relation between BC and CD is .
In △ABC,
AB+BC > AC
⇒ AB + BC > AD + CD
⇒ AB + BC > AB + CD (Since AB = AD)
⇒ BC > CD
In the figure below, if AC>AB and D is point on AC such that AB = AD, then the relation between BC and CD is BC>CD.
