Geometry Transformation Test Review

The video tutorial covers various geometric transformations, including rigid transformations, reflections, and rotations. It explains the differences between pre-images and images, and provides rules for performing transformations. The tutorial also demonstrates how to reflect shapes over axes and specific lines, and how to rotate shapes around the origin. Key concepts such as enlargement, transformation rules, and the effects of reflections on coordinates are discussed.

What is the main reason the transformation in question 5 is not considered a rigid transformation?

• The pre-image and image are different sizes.

• The pre-image and image are the same size.

• The pre-image and image are the same shape.

• The pre-image and image are both reflections.

What is the image of line segment ZE in the transformation discussed?

• Segment LA

• Segment ZW

• Segment FM

• Segment WE

How many units to the left and up does the transformation in question 6 move the pre-image?

• 5 units left, 7 units up

• 5 units left, 8 units up

• 4 units left, 8 units up

• 4 units left, 7 units up

What is the rule for the transformation in question 7?

• Move 5 units right and 10 units up

• Move 5 units right and 10 units down

• Move 5 units left and 10 units up

• Move 5 units left and 10 units down

When reflecting over the x-axis, which values change?

• Both X and Y values

• Y values

• Neither X nor Y values

• X values

What is the line of reflection for the transformation in question 10?

• X = 4

• Y = 2

• Y = 4

• X = 2

In the reflection over Y = X, what happens to the coordinates of a point?

• They remain the same

• They are doubled

• They are switched

• They are halved

What is the result of reflecting point (5, 0) over the line Y = X?

• (0, 5)

• (5, 5)

• (0, 0)

• (5, -5)

What are the coordinates of point R after a 180-degree rotation about the origin?

• (4, -1)

• (1, -4)

• (-4, 1)

• (-1, -4)

What is the pattern for the rule of a 180-degree rotation about the origin?

• (X, Y) -> (-Y, -X)

• (X, Y) -> (Y, X)

• (X, Y) -> (-X, -Y)

• (X, Y) -> (X, -Y)
