How to rotate a triangle counter clockwise 270 degrees

The video tutorial explains how to perform a 270-degree counterclockwise rotation of a triangle on a coordinate plane. It covers the rule for swapping and negating coordinates, applies this rule to find new points, and verifies the results by graphing. The tutorial also compares 270-degree counterclockwise rotation with 90-degree clockwise rotation, highlighting their equivalence.

What are the coordinates of the points after performing the transformations described?

Explain the relationship between a 270-degree counterclockwise rotation and a 90-degree clockwise rotation.
