How To Reflect The Figure In Photo Across The Yx Line class=

Sagot :

We need to reflect the figure across the y = x line. We know that for a reflection of a point across y = x, we have the property:

Now, for the vertices D, E and N of the triangle, we have the coordinates:

D = (-4, -2)

E = (-2, -3)

N = (-2, -5)

Using the property stated in the figure above, their coordinate reflections must be:

D' = (-2, -4)

E' = (-3, -2)

N' = (-5, -2)

The reflected figure is:
