What is a reflection in geometry?

Back

A reflection in geometry is a transformation that flips a figure over a line called the line of reflection.

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

Back

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

What is the rule for translating a point 2 units to the right and 1 unit down?

Back

The rule for this translation is (x + 2, y - 1).

What are the coordinates of point C after reflecting it over the y-axis if C is at (3, 2)?

Back

The coordinates of point C after reflecting over the y-axis will be (-3, 2).

What happens to the x-coordinates of points during a reflection over the y-axis?

Back

The x-coordinates of points are negated during a reflection over the y-axis.

What is the effect of translating a figure on its orientation?

Back

Translating a figure does not change its orientation; it simply shifts the figure to a new location.

What is the effect of reflecting a figure over the x-axis?

Back

Reflecting a figure over the x-axis negates the y-coordinates of the points.

Front

If a point is translated according to the rule (x + 0, y - 5), what happens to the y-coordinate?

Back

The y-coordinate is decreased by 5, while the x-coordinate remains unchanged.
