Question

If a triangle ABC is at: A = ( 1, 5 ) B = ( 6, 9 ) C = ( - 2, - 3 ) and if it is translated right 4 and down 7, find the new point A '.

a. ( 3, 4 )
b. ( -5, 2 )
c. ( 6,- 7)
d. ( 5,- 2)

Answer 1

answer is (d) (5, -2)

Explanation:

When a triangle is translated, each point is moved the same distance in the same direction. To translate a point right, we add the amount of units to the x-coordinate, and to translate it down, we subtract the amount of units from the y-coordinate.

So for point A, the original coordinates are (1,5) and it is translated right 4 and down 7. The new coordinates of point A' will be (1+4, 5-7) = (5,-2)
