Rigid Transformations

Front

What is a rigid transformation?

Back

A transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What happens to a shape when it is reflected over the y-axis?

Back

The x-coordinates of the points of the shape change sign, moving the shape to the opposite quadrant.

Front

If a shape in Quadrant 1 reflects over the y-axis, which quadrant will the reflection be in?

Back

Quadrant 2.

Front

What is translation in geometry?

Back

A transformation that moves every point of a shape the same distance in a specified direction.

Front

If a shape is translated up 3 units and left 6 units, what is the new position of the shape?

Back

The shape moves 3 units up and 6 units to the left from its original position.

Front

What does congruent mean in geometry?

Back

Congruent means having the same size and same shape.

Front

What symbol is used to indicate that two shapes are congruent?

Back

The symbol ≅ is used to show that two shapes are congruent.

Front

What is a reflection in geometry?

Back

A transformation that flips a shape over a line, creating a mirror image.

Front

If a shape in Quadrant 2 reflects over the x-axis, which quadrant will the reflection be in?

Back

Quadrant 3.

Front

What is a rotation in geometry?

Back

A transformation that turns a shape around a fixed point at a certain angle.
