Question

Define invariant points in reflection
​

Answer 1

$\large\bold\orange{\underline{Answer:-}}$

➻ In reflection,

• Points whose reflection lies on the point itself, is known as Invariant points...

Answer 2

Answer:

We know that only those points which lie on the line are invariant points when reflected in the line. So, only those points are invariant which are on the line parallel to the x-axis at a distance 4 on the positive side of the y-axis. Hence, the invariant points must have y-coordinate = 4.
