The mathematical statement of triangle law is called as Pythagorean theorem,

Answer 2

The correct solution for the given question is option d: Polygon rule.

• This law of the triangle is based on the principle of the quantization or addition of vectors.
• These vectors represent the side of the triangle.
• The sides of the triangle have a particular magnitude and direction and when they are in similar order their sum gives the remaining side with magnitude and reverse direction.
• This law is also called polygon law.
• According to this mathematical concept also if two vectors are drawn in the same order having a particular direction and having a magnitude of the measurement then its resultant vector on addition obtained is given by the closing side of the polygon.
• This forms a triangle when three vector quantities are produced which is a polygon.
• Hence, the correct answer is the polygon rule.
