The video tutorial covers four key geometric transformations: reflection, rotation, translation, and enlargement. Each transformation is explained in detail, including how to perform and describe them. Reflection involves using a mirror line, rotation requires a center and direction, translation uses vector notation, and enlargement needs a scale factor and center. The tutorial emphasizes the importance of understanding these concepts for geometry problems.

What is essential to perform a reflection of a shape?

• A vector notation

• A scale factor

• A mirror line

• A center of rotation

Which of the following is NOT required to describe a rotation?

• The direction of rotation

• The center of rotation

• The measure of turn

• The scale factor

In vector notation for translation, what does the top number represent?

• Direction along the y-axis

• Center of enlargement

• Direction along the x-axis

• Scale factor

What is the scale factor if a shape is enlarged from 3 units to 9 units?

• 3

• 4

• 2

• 1

What is the term for sliding a shape into a new position?

• Translation

• Reflection

• Rotation

• Enlargement
