Class 9 Mathematics | Ganita Manjari | Chapter 1 – Coordinate Geometry
In this video, we cover an IMPORTANT TOPIC of Coordinate Geometry — Finding the Coordinates of the Image of a Point After Reflection in the Cartesian Plane.
This concept is extremely important for Class 9 Maths exams and understanding coordinate geometry.
📌 In This Video, You Will Learn:
✅ Reflection of a point in the X-axis
✅ Reflection of a point in the Y-axis
✅ Reflection of a point in the Origin
✅ Reflection of a point in the X=Y
✅ How to find the coordinates of the image of a given point
✅ Important rules and formulas
✅ Step-by-step examples and exam-oriented questions
✅ Easy tricks to remember the changes in coordinates
📖 Important Rules:
Reflection in X-axis:
\((x, y) → (x, -y)\)
Reflection in Y-axis:
\((x, y) → (-x, y)\)
Reflection in Origin:
\((x, y) → (-x, -y)\)
🎯 Master this concept and solve reflection questions with confidence!
