Which of the following is the first step in composite transformation performed to scale a line with a fixed end point? a) Changing the position of the line so that the origin and the line’s endpoint overlaps b) Keeping the origin same and scaling the line with respect to the origin c) Changing the position of the line so that the endpoint and the fixed endpoint of the line overlaps d) Keeping the end point same and scaling the line with respect to the endpoint
Answer: a Explanation: The first step in composite transformation performed to scale a line with a fixed endpoint is to translating the line so that its end coincides with the origin. After this step only that endpoint is scaled which is not on the origin and then the non-scaled endpoint is translated back to its original position.
