Geometry builds the foundation for spatial reasoning. In this video, you will work through the unit activity introduction to geometry and transformations. The walkthrough breaks down core concepts into clear, manageable steps.
Transformations change the position, orientation, or size of a shape on a coordinate plane. You will explore four primary types: translations, reflections, rotations, and dilations. Translations slide a figure across the grid without turning it. Reflections flip a shape over a line of symmetry to create a mirror image. Rotations turn a figure around a fixed point by a set angle. Dilations change the size of the shape while preserving its overall proportions.
The video walks you through practical problems featured in this unit activity. You will see firsthand how coordinate pairs shift under each transformation rule. Pay close attention to how signs change across the x-axis and y-axis during reflections and rotations.
