## Using Vector Cross product to find Area of a Parallelogram

Let’s see how to use the Vector Cross product to find the Area of a Parallelogram. Here we will see that the magnitude of the cross product of vector AB and AC gives the area of the parallelogram ABCD. (reference: the image below) ABCD is a parallelogram and its area is twice the area of […]

## Using the Vector Cross product to find the Area of a Triangle

Let’s see how to use the Vector Cross product to find the Area of a Triangle. Here we will see that half of the magnitude of the cross product of vector AB and AC gives the area of the triangle ABC. (reference: the image below) Let, AB and AC are 2 vectors and these are […]

## Vector Product

The vector product of two vectors A and B, also called the cross product, is denoted by A X B, and the magnitude of the vector product is found using the formula AB sinφ. Here, A and B are magnitudes of vectors A and B respectively and φ is the angle between the two vectors. […]
