cross product of vectors to find the area of triangle

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

By Anupam M

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 […]
