In 2D-translation, a point (x, y) can move to the new position (x’, y’) by using the equation
A. x’=x+dx and y’=y+dx
B. x’=x+dx and y’=y+dy
C. X’=x+dy and Y’=y+dx
D. X’=x-dx and y’=y-dy
Answer:A
In 2D-translation, a point (x, y) can move to the new position (x’, y’) by using the equation
A. x’=x+dx and y’=y+dx B. x’=x+dx and y’=y+dy C. X’=x+dy and Y’=y+dx D. X’=x-dx and y’=y-dy
Explanation: By adding translation distance dx and dy to its originsl position (x, y) we can obtain a new position (x’, y’).
