Step-by-step explanation:
Two figures are congruent if they have the same size and shape. In this case, figure B is greater than figure A, so they are not congruent.
However, Figures C and D are congruent and we can map figure C to D by a rotation of 90 degrees counterclockwise about the origin. For example, the point (2, 3) of figure C becomes point (-3, 2), so the rule is
(x, y) ---> (-y, x) which is the rule for a 90 degrees rotation counterclockwise.
Answers:
Are figure A and B congruent? No
Which transformation maps A to B? None of these
Are figure C and D congruent? Yes
Which transformation maps C to D? Rotate figure C counterclockwise 90 about the origin.
