Geometry Transformations Practice

Describe the transformation shown in the graph.

(Black shape is the pre-image)

• Reflect across $x=-2$  

• Translate 2 units right

• Reflect across  $y=-2$  

Describe the transformation shown in the graph.

(Black shape is the pre-image)

• Reflect across $y=1$

• Reflect across the y-axis

• Reflect across the x-axis

Fill-in-the-Blank to describe the transformation shown in the graph: 

"Translate one unit _______"

(Black shape is the pre-image)

What is a translation?

• When you turn an object around a point.

• When you slide an object from one place to another.

• When you flip or mirror an object across a line.

• When you resize an object.

What is a reflection?

• When you turn an object around a point.

• When you slide an object from one place to another.

• When you flip or mirror an object across a line.

• When you resize an object.

What do we call... The original object before geometric transformations.

(Hint: it is usually labeled using prime symbols, such as ABC)

• pre-image

• original

• image

• unique

What do we call... The object after geometric transformation(s) have occurred.

(Hint: it is usually labeled using prime symbols, such as A’B’C')

• pre-image

• original

• image

• unique

Identify the transformation from C to D.
