Write the coordinates of the vertices after a reflection over the line x=-2 d(-10,0)
e(-10,2)
f(-5,2
g(-5,0)

Given:

The vertices are d(-10,0), e(-10,2), f(-5,2) and g(-5,0).

To find:

The coordinates of the vertices after reflection over the line x=-2.

Solution:

If figure reflected over the line x=a, then

Here, the figure is reflected over the line x=-2, then

          ...(i)

Now,

For point d,

Similarly,

For point e,

For point f,

For point g,

Therefore, the coordinates of vertices after a reflection over the line x=-2 are d prime (6,0), e prime (6,2), f prime, (1,2) and g prime (1,0).
