Mrs. Kim's Transformations in Geometry Flashcard

Front

What are the new coordinates of a point (x, y) after a 360-degree rotation about the origin?

Back

(x, y)

Front

What are the new coordinates of a point (x, y) after reflecting over the line y = -x?

Back

(-y, -x)

Front

What is the definition of Translation in geometry?

Back

Translation is a transformation that slides a figure from one position to another without rotating or flipping it.

Front

What are the new coordinates of the point (-3, 7) after reflecting over the y-axis?

Back

(3, 7)

Front

Which transformation changes the size of a geometric figure?

Back

Dilation

Front

What is the definition of Reflection in geometry?

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the definition of Rotation in geometry?

Back

Rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the definition of Dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure while maintaining its shape.

Front

If a point (x, y) is translated 3 units to the right and 2 units up, what are the new coordinates?

Back

(x + 3, y + 2)

Front

What happens to the coordinates of a point (x, y) when it is reflected over the x-axis?

Back

(x, -y)
