I am stuck with the following problem that says :
$O$ is any point inside $\triangle ABC$. Then I have to prove that
- $AB+AC \gt OB+OC$
- $AB+BC+CA \gt OA+OB+OC$
From $\triangle ABC$,$AB+AC \gt BC$ and from $\triangle OBC\,\,$,we get $\,\,OB+OC \gt BC$. Now ,I am not sure about how to proceed.
Considering the $\triangle AOB$,$\triangle BOC $,$\triangle AOC$, we get
$OA+OB \gt AB\,\,,OB+OC \gt BC\,\,,OC+OA \gt AC\,\, $ respectively.
Now, combining all we get $2(OA+OB+OC) \gt (AB+BC+CA)$.
So,I am nowhere near the proof. Can someone point me in the right direction? Thanks in advance for your time.

For 1. :
Let $E$ be a point both on $OB$ and on $AC$.
From $\triangle{ABE}$, $$AB+AE\gt BO+OE\tag1$$
From $\triangle{OEC}$, $$OE+EC\gt OC\tag2$$
Now the claim follows from $(1)+(2)$.
For 2. :
You can use 1. to prove that the inequality holds.
