1. A translation is applied to an object by
a) Repositioning it along with straight line path
b) Repositioning it along with circular path
c) Only b
d) All of the mentioned
View Answer
Answer: a
Explanation: A translation is applied to an object by repositioning it along with straight line
path from one location to another.
2. We translate a two-dimensional point by adding
a) Translation distances
b) Translation difference
c) X and Y
d) Only a
View Answer
Answer: d
Explanation: We can translate 2D point by adding translation distances dx and dy.
3. The translation distances (dx, dy) is called as
a) Translation vector
b) Shift vector
c) Both a and b
d) Neither a nor b
View Answer
Answer: c
Explanation: The translation distances (dx, dy) from its original position is called as
translation vector or shift vector.
4. 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
View Answer
Answer: b
Explanation: By adding translation distance dx and dy to its originsl position (x, y) we can
obtain a new position (x’, y’).
5.The two-dimensional translation equation in the matrix form is
a) P’=P+T
b) P’=P-T
c) P’=P*T
