Understanding Translations in Geometry

The video tutorial explains the concept of transformations, focusing on translations. It describes how a pre-image is moved to a new position without rotation, using horizontal and vertical shifts. An example is provided, demonstrating how to graph a triangle and its translated image using specific coordinate changes.

What is the result of a transformation in geometry?

• A reflected figure

• A scaled figure

• A new figure called the image

• A rotated figure

In a translation, how does a figure move?

• It rotates around a point

• It flips over a line

• It enlarges or shrinks

• It slides from one position to another
