Question

Reflect triangle A in the line y=x

please can you just state all the coordinates to make up the triangle

Answer 1

(5,6), (3, 6) and (3, 5).

Explanation:

If we imagine the line y = x to be a mirror , the image of each point is the same perpendicular distance to the mirror has the original point.

So the image of (6,5) = (5,6)

(6, 3) ---> ( 3, 6)

(5,3) ---> (3, 5).

Note that the coordinates are reversed in each case.

In this case the general rule for the reflection is (x, y) ---> (y, x).
