Reflections

Front

What is a reflection in geometry?

Back

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

Front

What are the coordinates of a point reflected over the x-axis?

Back

If a point has coordinates (x, y), its reflection over the x-axis will be (x, -y).

Front

What are the coordinates of a point reflected over the y-axis?

Back

If a point has coordinates (x, y), its reflection over the y-axis will be (-x, y).

Front

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

Back

The coordinates of a point (x, y) reflected over the line y = x become (y, x).

Front

What happens to the coordinates of a point reflected over the origin?

Back

If a point has coordinates (x, y), its reflection over the origin will be (-x, -y).

Front

What is the line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.

Front

True or false: The distance from a point to the line of reflection is the same as the distance from its reflection to the line.

Back

True.

Front

What is the reflection of the point (4, 2) over the x-axis?

Back

The reflection is (4, -2).

Front

What is the reflection of the point (-3, 5) over the y-axis?

Back

The reflection is (3, 5).

Front

If a quadrilateral ABCD is reflected over the x-axis, what happens to the coordinates of point B (2, 3)?

Back

Point B will be reflected to (2, -3).
