Front

What is Reflection in geometry?

Back

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

Front

What is Translation in geometry?

Back

Translation is a transformation that slides a figure from one position to another without changing its shape or orientation.

Front

What is Rotation in geometry?

Back

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

Front

What is Dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape the same.

Front

What are Transformations in geometry?

Back

Transformations are operations that alter the position, size, or shape of a figure.

Front

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

Back

The coordinates become (x, -y).

Front

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

Back

The coordinates become (-x, y).

Front

What is the result of a 90° clockwise rotation of a point (x, y)?

Back

The new coordinates will be (y, -x).

Front

What is the result of a 90° counterclockwise rotation of a point (x, y)?

Back

The new coordinates will be (-y, x).

Front

If a triangle is translated 3 units to the right and 2 units up, what are the new coordinates of the point (1, 1)?

Back

The new coordinates will be (4, 3).
