 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Two successive translations are ____ a) b) c) d)
 A Subtractive B Additive C Inverse D Multiplicative
Explanation:

Detailed explanation-1: -Explanation: Successive translations are additive.

Detailed explanation-2: -2D Translation is a process of moving an object from one position to another in a two dimensional plane. Consider a point object O has to be moved from one position to another in a 2D plane. Tx defines the distance the Xold coordinate has to be moved. Ty defines the distance the Yold coordinate has to be moved.

Detailed explanation-3: -Transformation means changing some graphics into something else by applying rules. We can have various types of transformations such as translation, scaling up or down, rotation, shearing, etc. When a transformation takes place on a 2D plane, it is called 2D transformation.

Detailed explanation-4: -A number of transformations or sequence of transformations can be combined into single one called as composition. The resulting matrix is called as composite matrix. The process of combining is called as concatenation.

Detailed explanation-5: -2D Translation in Computer Graphics The translation is repositioning an object along a straight-line path from one coordinate location to another coordinate location. The translation is the rigid body transformation that saves an object without deformation. A translation moves to a different position on the screen.
