Mathematics — first biennium · Lesson
Translations, reflections and rotations move figures while preserving distances and angles; coordinates change according to precise rules.
Prerequisites: Coordinates and quadrilaterals
Goal: Recognize translations, reflections and rotations and apply coordinate rules.
In this lesson: Recognize translations, reflections and rotations and apply coordinate rules.
How to proceed: Compare the coordinate rule with the basic models: a translation adds one fixed vector; a reflection changes a sign; a rotation swaps coordinates with controlled signs.
You can already assume: Coordinates and quadrilaterals.

Compare the coordinate rule with the basic models: a translation adds one fixed vector; a reflection changes a sign; a rotation swaps coordinates with controlled signs.
Data / situation: P(0,-3) is transformed by (x,y)→(−y,x).
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
