Transformations in math refer to the changes made to the position or size of a shape on a coordinate plane. One common type of transformation is translation, which involves sliding a shape from one location to another without changing its size, shape, or orientation. For example, if you have a triangle with vertices at (1, 2), (3, 4), and (5, 2), and you want to translate it 3 units to the right and 2 units up, you would add 3 to the x-coordinates and 2 to the y-coordinates of each vertex.

📖 2 of 2

This means the new vertices would be at (4, 4), (6, 6), and (8, 4). Translations can be represented using vector notation, such as (3, 2), which indicates the direction and distance of the slide. Understanding translations helps in visualizing how shapes move on a plane and is foundational for more complex transformations.
