What transformation is shown below? (Look carefully at the vertices.)

translation

Answers

This is translation.

The figure shows reflection.

What is transformation?

Four distinct ways to alter the shape and/or position of a point, line, or geometric figure are collectively referred to as transformations. The object's final shape and location are referred to as the Image under the transformation, while the Pre-Image is its original form.

Different types of transformation are reflection, rotation, and translation.

Given a graph,

condition for Translation: translation is when any figure not change its shape, size and orientation and can be any direction.

Condition for Rotation: without changing the size and shape of any object and rotate about a fixed point is rotation.

Condition for reflection: without changing shape and size of any object and flip it across a line.

Hence according to the question the figure is flip across a line without changing its size and shape, so it is reflection.
