Understanding Reflections in Geometry

When reflecting a point across the line y = -1, what happens to the x-coordinate of the point?

• It doubles.

• It remains the same.

• It becomes zero.

• It is inverted.

What is the effect on the y-coordinate of a point when it is reflected across the x-axis?

• It is inverted.

• It becomes zero.

• It remains the same.

• It doubles.

When reflecting a triangle across the x-axis, what happens to the x-coordinates of the vertices?

• They become zero.

• They are inverted.

• They remain unchanged.

• They double.

In a reflection across the line y = x, how do the coordinates of a point change?

• The x and y coordinates are swapped.

• Both coordinates are inverted.

• The x-coordinate is doubled.

• The y-coordinate becomes zero.

What is a key characteristic of reflections across the line y = x?

• The x-coordinates remain unchanged.

• The points move to the origin.

• The y-coordinates are inverted.

• The coordinates are swapped.
