Slide, Flip, Turn: Geometric Transformations

Front

What is a geometric transformation?

Back

A geometric transformation is a change in the position, size, or shape of a figure in a geometric space.

Front

What does it mean to slide a shape?

Back

To slide a shape means to move it from one position to another without changing its size, shape, or orientation. This is also called a translation.

Front

What is a flip in geometric transformations?

Back

A flip is a transformation that creates a mirror image of a shape over a line, known as the line of reflection.

Front

What is a turn in geometric transformations?

Back

A turn is a transformation that rotates a shape around a fixed point, known as the center of rotation.

Front

Can you give an example of a slide?

Back

If you have a triangle at point (2, 3) and you slide it 4 units to the right and 2 units up, it will move to point (6, 5).

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create a mirror image.

Front

What happens to a shape when it is turned 90 degrees clockwise?

Back

When a shape is turned 90 degrees clockwise, each point of the shape moves to a new position that is 90 degrees around the center of rotation.

Front

What is the difference between a slide and a flip?

Back

A slide moves a shape without changing its orientation, while a flip creates a mirror image of the shape.

Front

What is an example of a turn?

Back

If you have a square and you turn it 180 degrees around its center, the square will look the same but will be in a different orientation.

Front

What does it mean for a transformation to be congruent?

Back

A transformation is congruent if the original shape and the transformed shape are the same size and shape.
