Question

Based on the points and their images given below, match the following with respect to their transformation.

• A. Reflection in origin
• B. Reflection in y-axis
• C. Reflection in x-axis
• D. Invariant point

Answer 1

(5,-7) to (-5,7) Here both abscissa and ordinate are changing their signs. This happens when a point is reflected in origin.

(4,-8) to (-4,-8) Here, only sign of abscissa is changed. This is possible when a point is reflected in y-axis.

(4,2) to (4,-2) Here, only sign of ordinate is changed. This implies point is reflected in x-axis.

(0,6) to (0,6) Here, image of a point is the point itself i.e it is invariant point and is reflected on y-axis.
