Define Reflection with respect to coordinate geometry?

Jyoti replied | 06/12/2016

In Mathematics, a reflection (also spelled reflexion) is a mapping from a Euclidean space to itself that is an isometry with a hyperplane as a set of fixed points, this set is called the axis or plane of reflection.

In coordinate geometry reflection is given as below
In this all the points (x,y) go to the points (x,-y). i.e. the plane above X-axis gets mapped below X-axis & vice versa.
Example: If P(1,3) is a point in 1st quadrant then under reflection about X-axis it goes to P*(1,-3) in 4th quadrant.

In this all the points (x,y) go to the points (-x,y). i.e. the plane on the right of Y-axis gets mapped to left of Y-axis.
Example: If P(1,3) is a point in 1st quadrant then under reflection about Y-axis it goes to P*(-1,3) in 2nd quadrant.

Similarly, we can define reflection about the lines y=x, y=-x.
In General, we can define reflection about any line in plane. «less

Kapil replied | 20/11/2016

One half of the reflection is of the other half is defined as reflection symmetry.

What is line of symmetry?

0 0 3

T Raghavender replied | 25/11/2016

It's a line passing figure on a plane and dividing it into two parts such that one part is mirror image of the other part.

Chandan replied | 05/12/2016

The "Line of Symmetry" (shown here in white) is the imaginary line where you could fold the image and have both halves match exactly.
