TRANSLATIONS REFLECTION ROTATIONS TEST

Front

What is a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in a specified direction.

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

What does it mean to rotate a figure?

Back

To rotate a figure means to turn it around a fixed point, called the center of rotation, by a certain angle.

Front

What is the rule for rotating a point 90 degrees counterclockwise?

Back

The rule is (x, y) → (-y, x).

Front

What is the rule for rotating a point 180 degrees?

Back

The rule is (x, y) → (-x, -y).

Front

What is the rule for rotating a point 270 degrees counterclockwise?

Back

The rule is (x, y) → (y, -x).

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

How do you translate a figure 5 units to the right?

Back

To translate a figure 5 units to the right, add 5 to the x-coordinate of each point.

Front

What are the coordinates of point A if it is at (2, 7)?

Back

The coordinates of point A are (2, 7).

Front

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

Back

When reflected over the y-axis, the new point will be (-x, y).
