2.
FLASHCARD QUESTION
Front
Define dilation in the context of similarity transformations.
Back
Dilation is a transformation that changes the size of a figure by a scale factor relative to a center point, while maintaining the shape of the figure.

FLASHCARD QUESTION
Front
What is the effect of a reflection across the x-axis on a point (x, y)?
Back
The reflection across the x-axis transforms the point (x, y) to (x, -y).
4.
FLASHCARD QUESTION
Front
What is the effect of a reflection across the y-axis on a point (x, y)?
Back
The reflection across the y-axis transforms the point (x, y) to (-x, y).

FLASHCARD QUESTION
Front
How do you perform a translation of a point (x, y) by (a, b)?
Back
To translate the point (x, y) by (a, b), you add a to the x-coordinate and b to the y-coordinate, resulting in the new point (x+a, y+b).

FLASHCARD QUESTION
Front
What is the result of rotating a point (x, y) 90 degrees counterclockwise around the origin?
Back
The rotation of a point (x, y) 90 degrees counterclockwise around the origin transforms it to (-y, x).
