Learning Goal
Part of: Experiment with transformations in the plane — 2 of 5 cluster items
Represent and describe transformations
**HSG.CO.A.2**: Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).

HSG.CO.A.2: Represent transformations in the plane using, e.g., transparencies and geometry software; describe transformations as functions that take points in the plane as inputs and give other points as outputs. Compare transformations that preserve distance and angle to those that do not (e.g., translation versus horizontal stretch).
What you'll learn
- Represent transformations in the plane using transparencies, geometry software, or coordinate rules
- Describe transformations as functions that map input points to output points
- Identify the four basic transformations: translation, rotation, reflection, and dilation
- Distinguish between rigid motions (distance- and angle-preserving) and non-rigid transformations (those that do not preserve distance or angle)
- Predict the effect of a given transformation on a figure by reasoning about distance and angle preservation
