A parallelogram is drawn and then rotated 90°. Which statement is true? A) The two parallelograms are congruent because all para
llelograms are congruent. B) The two parallelograms are not congruent because a rotation changes side length. C) The two parallelograms are not congruent because a rotation changes angle measures. D) The two parallelograms are congruent because a rotation does not change size and shape. A parallelogram is drawn and then rotated 90°. Which statement is true?

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.
If you're talking about a 6-sided die, then there are 6 sides. Rolling a 2 or a 3 would be a 2/6 chance. To simplify if from there, you can also say that there is a 1/3 chance.
