Exploring Transformation Types and Rotation Rules

The video provides a comprehensive review of transformations, focusing on rigid and non-rigid motions. It explains the concepts of translations, reflections, and rotations, detailing how each affects the location and orientation of shapes on a coordinate grid. The video also introduces non-rigid motion, specifically dilations, which change the size of shapes while maintaining similarity. Detailed rules for rotations at various angles are discussed, and the video concludes with information about upcoming tests and assessments.

What does rigid motion ensure about the shape of objects?

• Alters the size

• None of the above

• Changes the shape

• Maintains congruency

What type of transformation is described by a slide movement?

• Rotation

• Dilation

• Reflection

• Translation

Which axis can a reflection occur over?

• None of the above

• Both X-axis and Z-axis

• X-axis or Y-axis

• Z-axis

What happens to coordinates in a 90-degree rotation counterclockwise?

• X and Y coordinates swap and Y becomes negative

• X and Y coordinates swap and X becomes negative

• No changes occur

• X becomes Y and Y becomes X

What is the rule for a 180-degree rotation?

• X and Y coordinates halve

• X and Y coordinates become negative

• X and Y coordinates swap

• X and Y coordinates double

What does a dilation in non-rigid motion affect?

• Shape orientation

• Shape position

• Shape size

• Shape color

What is similar between a 90-degree counterclockwise and a 270-degree clockwise rotation?

• Both change the shape

• Both are types of translations

• Both result in the same coordinate transformation

• Both alter the size of the shape
