Answer:
The sum of the three angles of any triangle is equal to 180 degrees.
If A is the set of all triangles defined in a plane whose sum of measures of all angles is less than 180 degrees, then,
A = \{ \} = \emptysetA={}=∅
Because, any triangle defined in a plane has a sum of all angles to be exactly equal to 180 degrees.
