Question

According to the Triangle Law of Vector Addition, if two vectors are represented by two sides of a triangle taken in order, how is their sum represented?

Options

• By the diagonal passing through their common initial point

• By the perpendicular bisector of the first side

• By the third side of the triangle taken in the same order

• By the third side of the triangle taken in the opposite order

Answer 1

The Triangle Law of Vector Addition states that if two vectors are represented by two sides of a triangle taken in order (head-to-tail arrangement), their sum is represented by the third side taken in the opposite order, giving \[\vec{AB} + \vec{BC} = \vec{AC}\].
