Translate and Reflect

Front

What are congruent geometric figures?

Back

Congruent geometric figures have the same size and same shape.

Front

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

Back

To reflect the point (-1, 2) over the y-axis, change the sign of the x-coordinate: (1, 2).

Front

What transformation occurs when a figure is reflected across the x-axis?

Back

The y-coordinates of the points are negated.

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

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

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

Back

The y-coordinate changes sign, while the x-coordinate remains the same.

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

Back

The x-coordinate changes sign, while the y-coordinate remains the same.

Front

Identify the transformation: A triangle is flipped over the line y=x.

Back

Reflection across the line y=x.

Front

Identify the transformation: A square is moved 3 units to the right and 2 units up.

Back

Translation.

Front

What is the result of reflecting the point (3, -4) over the y-axis?

Back

(-3, -4).
