Question

If Triangle ABC has been translated 4 units to the right into Triangle DEF, what are the coordinates of Point E?

Answer 1

D(6, -2)

Explanation:

You want the coordinates of point E in ∆DEF congruent to ∆ABC after, it has been translated 4 units to the right.

Corresponding points

The triangle names tell us that point E is the image of point B after the translation.

Translation

Moving a point to the right 4 units adds 4 to its x-coordinate.

B(2, -2) ⇒ E(2+4, -2) = E(6, -2)
