A mirror is placed vertically such that it passes through the points (10, 0) and (0, 10). Find the reflected coordinates of a triangle ABC with coordinates A(5, 50), B(20, 40) and C(10, 70).

When a vertical mirror is positioned such that it passes across the points (10, 0) and (0, 10), the reflected image of the triangle ABC with its coordinates will shift up by 10%.
Hence ,
It is a transformation that creates an object's mirror image. Either the x-axis or the y-axis can be the subject of the mirror image. The thing is 180 degrees turned.
Mirroring off the x-axis
Inverse reflection on the y-axis
reflection about an axis going through the origin and perpendicular to the x-y plane
Consideration of the line y=x
Reflection about the x-axis: The following matrix can be used to reflect the item about the x-axis.
The value of x will remain unchanged in this transformation, but the value of y will turn negative.
