Given a wire 20 cm long. Is it possible to bend a triangle from it, one side of which would be 12 cm?

You can’t.
According to the basic properties of a triangle, in absolutely any triangle, any of the sides is less than the sum of the other two sides.
Therefore, if one side is 12 cm, then the sum of the other two must be greater than 12. That is, the wire must be more than 24 cm, which does not meet the condition.
