angle P = 70°
angle R =30°
then,
angle Q = 180°-(70+30)°
= 80°
as you can see that the largest angle is angle Q so, the largest angle must be opposite to it.
So, PR is the longest side.
angle R =30°
then,
angle Q = 180°-(70+30)°
= 80°
as you can see that the largest angle is angle Q so, the largest angle must be opposite to it.
So, PR is the longest side.

you might have read the theorem which states that the side opposite to the largest angle in a traingle is longest
this theorem is in 9th standard.. man
