What are transformations and the different types

The video tutorial discusses transformations in geometry, focusing on congruent transformations where the shape and size remain unchanged. It covers three main types: translation, reflection, and rotation. Translation involves sliding a figure using a translation vector. Reflection flips a figure over a line of symmetry. Rotation turns a figure around a point, often the origin, and can be clockwise or counterclockwise. The tutorial emphasizes that these transformations alter the position and orientation but not the shape or size of the figures.
