Understanding Triangle Rotation

The video tutorial explains how to rotate a triangle by negative 60 degrees. It begins with a review of the difference between positive and negative angles, using a clock analogy to describe clockwise and counterclockwise rotations. The tutorial then demonstrates how to approximate a 60-degree rotation using an X and Y graph, emphasizing the importance of understanding the direction of rotation. The explanation includes visual aids and practical tips for estimating angles on a graph.

What is the main problem discussed in the video?

• Drawing a triangle on a graph

• Finding the perimeter of a triangle

• Rotating a triangle by negative 60 degrees

• Calculating the area of a triangle

How does a positive angle affect the direction of rotation?

• It rotates in a random direction

• It does not affect rotation

• It rotates counterclockwise

• It rotates clockwise
