2, 2, 3 can be lengths of the sides of a triangle. true or false

True

Step-by-step explanation:

The sides a=2, b=2, c=3 of a triangle must obey the conditions:

a>0  ok

b>0  ok

c>0  ok

a+b>c  (2+2 > 3)  ok

b+c >a  (2+3 > 2)  ok

c+a >b  (3+2 > 2)  ok

So  2,2,3 can be the sides of a triangle.
