I think the correct answer would be D. The two parallelograms are congruent because a rotation does not change size and shape.

Answer: D) The two parallelograms are congruent because a rotation does not change size and shape.


Step-by-step explanation:

Rotation transformation is a rigid transformation which create the image of a figure with same shape and size by rotating it by some degrees about the the center of rotation. It doesn't change size and shape of the figure.

When we rotate a figure about a point and if it doesn't change the shape then it is called rotational symmetry.

Therefore, only D is the right option.

The width of the rectangle is 75% of its length. The length is 8 cm. What is the width of the rectangle?
hjlf

Given :

The length of the rectangle, l = 8 cm/

The width of the rectangle, w = 75% of 8 cm

                                                 $= \frac{75}{100} \times 8$

                                                 $=\frac{15}{20} \times 8$

                                                 = 0.75 x 8

                                                 = 6

Therefore, the width of the rectangle is 6 cm.
