UNIT 3 Final REVIEW - Geo

Front

What is a translation in geometry?

Back

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

Front

Which coordinate is affected by movement up and down on a coordinate plane?

Back

The y-coordinate.

Front

What is the reflection of 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 reflection of 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

If point C is at (3, 2), what is its reflection over the y-axis?

Back

(-3, 2).

Front

If point D is at (5, -5), what is its reflection over the x-axis?

Back

(5, 5).

Front

What does it mean to reflect a shape across the x-axis?

Back

It means to flip the shape over the x-axis, changing the sign of the y-coordinates.

Front

Back

It means to flip the shape over the y-axis, changing the sign of the x-coordinates.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis).

Front

What is the rule for translating a figure 5 units right and 3 units up?

Back

Add 5 to the x-coordinates and 3 to the y-coordinates of each point.
