Reflections

Front

What is a reflection in geometry?

Back

A reflection is when you flip or mirror an object across a line.

Front

How do you reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, the new point will be (x, -y).

Front

How do you reflect a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, the new point will be (-x, y).

Front

What is the line of reflection?

Back

The line of reflection is the line across which a figure is flipped to create a mirror image.

Front

If point A is at (3, 4), where is A' after reflecting over the x-axis?

Back

A' is at (3, -4).

Front

If point B is at (-5, 2), where is B' after reflecting over the y-axis?

Back

B' is at (5, 2).

Front

What transformation occurs when a shape is flipped over a line?

Back

Reflection.

Front

What is the result of reflecting the point C(1, -3) over the line y = x?

Back

C' is at (-3, 1).

Front

What happens to the coordinates of a point when it is reflected over the line y = x?

Back

The x and y coordinates are swapped.

Front

If point D(0, 0) is reflected over any line, where will it be?

Back

It will remain at (0, 0) because it is on the line of reflection.
