What is a translation in geometric rigid transformations?

• Changing the size of a figure without moving it

• Rotating a figure around a fixed point

• Movement of a figure from one location to another without any rotation or reflection

• Flipping a figure over a line

Define reflection in the context of geometric rigid transformations.

• A transformation that rotates a figure

• A transformation that stretches a figure

• A transformation that flips a figure over a line, creating a mirror image.

• A transformation that shrinks a figure

Explain the concept of rotation in geometric rigid transformations.

• The movement of an object around a fixed point.

• The movement of an object in a straight line

• The act of reflecting an object across a line

• The process of changing the size of an object

What is the result of composing two translations in geometric transformations?

• a rotation

• a dilation

• a translation

• a reflection

How does the image change when an object is reflected over the x-axis?

• The image is flipped diagonally

• The image is flipped vertically

• The image is rotated 90 degrees

• The image is stretched horizontally

What are the properties of a shape that make it symmetrical?

• Unequal sides and angles

• Different sides and angles

• Equal sides and angles

• No sides or angles

What is the concept of composition of transformations.

• The composition of transformations is the process of applying multiple transformations to an object in a specific order.

• The composition of transformations is the process of removing transformations from an object.

• The composition of transformations is the process of applying transformations randomly to an object.

• The composition of transformations is the process of applying a single transformation to an object.

What is the rule used to transform △ABC to its image?

A(−3, 5), B(2, 8), C(−4, −5) and A'(−3, −5), B'(2, −8), C'(−4, 5)

Suppose the equation of line s is y = 2. What are the coordinates of C' of △A'B'C' for R_s?

• (1, 5)

• (2, 2)
• (-3, 5)

• (-1, 2)

After a reflection, the image vertices are A'(5, 1), B'(3, −1), and C'(7, −1). What is the line of reflection?
