### Reflection of Point in Y-Axis

Reflection of Point in Y-Axis A reflection can be thought of as folding or “flipping” an object over the line of reflection. An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, wi.....

### Reflection of Point in X-Axis

Reflection of a Point in the x-axis A reflection can be thought of as folding or “flipping” an object over the line of reflection. When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed).....

### Reflection of a Point in a Line

Reflection of a Point in a Line A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a […]

### Position of a Point in a Plane

Position of a Point in a Plane We know that the position of a point in a plane is given by its coordinates. In the adjoining figure, XOX’ and YOY’ are two intersecting and mutually perpendicular straight lines. Together, the two lines form the frame of reference in the Cartesian x-y plane for.....
