Question

Figure B is a rotation of Figure A about point C.

Which of the following is true?

A. The two figures are congruent.
B. Figure A is a translation.
C. The two figures are similar but not congruent.
D. Figure B is a dilation.

Answer 1

A. The two figures are congruent.

Explanation:

Shapes are congruent if you can turn one into the other by moving, rotating or flipping. These two shapes are rectangles. A rectangle is a quadrilateral whose angles are all right angles. So if you take rectangle A, and rotates it 90 degrees, then moving it to match rectangle B, you can realize that these two rectangles are the same shape.
