Detailed Solution

Given a statement, “all the angles of a triangle can be less than 60°.”
Triangles cannot include any angles smaller than 60° since their sum would not reach 180° if they did.
Since all three triangle angles add up to 180 degrees,
We know that, A+B+C< 180  .
Hence, all the angles of a triangle cannot be less than 60°.
Given statement is false.
Hence, option 2 is correct.
