Lesson
When reflecting across the line y = x, the coordinates of a point swap places: (x, y) becomes (y, x). Reflection across the line y = −x results in swapping and negating the coordinates: (x, y) becomes (−y, −x). These special reflections are essential in understanding symmetry between quadrants.
Learning objectives
Understand reflection in y = x and y = -x in the Reflection chapter.
Connect the idea with formulas, examples, and exam-style questions.
Use flashcards, notes, MCQs, and LAQs to check readiness.
