Exploring Transformations and Rotations in Geometry

Miss Smith's math tutorial covers the concept of rotations as a type of transformation. The video explains different types of rotations, including 90 degrees counterclockwise, 180 degrees, and 270 degrees counterclockwise, and provides rules for each. Practical examples are used to demonstrate these rotations, and students are given an exercise to practice rotating points 180 degrees.

What is the transformation rule for rotating a point 90 degrees counterclockwise?

• X, Y becomes Y, -X

• X, Y becomes Y, X

• X, Y becomes -Y, X

• X, Y becomes -X, -Y

What is the result of rotating a point 180 degrees, regardless of the direction of rotation?

• The point's coordinates swap places

• The point moves to a new quadrant

• The point's coordinates are both negated
