Rotating a triangle 90 degrees counter clockwise

The video tutorial explains how to rotate a triangle 90 degrees counterclockwise about the origin. It begins with plotting the original points of the triangle, labeled J, K, and L. The instructor clarifies the assumed direction of rotation and the point of rotation. The process involves swapping the coordinates and negating the first coordinate to achieve the rotation. Finally, the new positions of the rotated points are plotted, completing the rotation process.
