Translation and reflections

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

What does a translation do to a figure on the coordinate plane?

Back

It slides the figure to a new location without changing its shape or orientation.

Front

How do you describe a translation?

Back

A translation can be described by the direction and distance it moves a figure, such as '6 units right and 3 units up'.

Front

What happens to the coordinates of a point (x, y) when it is translated 2 units left and 3 units up?

Back

The new coordinates will be (x-2, y+3).

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

If a point (x, y) is reflected over the x-axis, what are the new coordinates?

Back

The new coordinates will be (x, -y).

Front

If a point (x, y) is reflected over the y-axis, what are the new coordinates?

Back

The new coordinates will be (-x, y).

Front

What quadrant will a point in quadrant 3 be in after reflecting over the x-axis?

Back

It will be in quadrant 2.

Front

What is the result of reflecting the point (-3, -7) over the y-axis?

Back

The new point will be (3, -7).

Front

What is the combined effect of reflecting a point and then translating it?

Back

The point will first be flipped over the specified line and then moved according to the translation.
