The statement is a negation because the sentence is false. All angles are NOT right angles and triangles do NOT have four sides.

Answer: negation.

Step-by-step explanation: In a triangle, all angles cannot be right angles, because if it is so, then 90°+90°+90°=270°>180°. Hence, not possible. Also, a triangle has only three sides, so the sentence that a triangle has four sides is also not correct.

So, the given statement is a combination of two negative statements, and so, it is negation.

Thus, the correct answer is negation.
