Reflection - Think mirror line
On any mathematical reflection question, think..
Where shall I put my mirror line
Reflection think mirror.
On a reflection the images are the same size and the same distance from the mirror line.
SAME SIZE AND DISTANCE FROM THE MIRROR LINE.
The object and the image are perpendicular (90°) to each other.
Create a reflection of the following triangle using the mirror line.
We would tackle this problem by measuring each point to the mirror at 90°.
Now we continue the line and measure the same distance to the other side of the mirror line.
Now we connect the dots.
This should leave you a perfect reflection:
We can now label the new image with the standard convention of `W^1,\ X^1 \ and\ Y^1`.
