Question

In the given figure, prove that:

CD + DA + AB > BC

Answer in Brief

Solution

We have to prove that CD + DA + AB > BC

In  ΔACD we have

CD + DA > CA (As sum of two sides of triangle is greater than third one)

 ⇒ CD + DA + AB > CA + AB (Adding  AB both sides)

CD + DA + AB > BC Proved.
