Which pairs of polygons are congruent?
Ronch [10]

The <em><u>correct answer</u></em> is:

pairs 2, 3, and 4

Explanation:

Congruent polygons are polygons that have the same size and the same shape.  We can see from the diagram that the figure in pair 2 has been rotated to form the second figure in the pair.  Since the shape and size were not changed, they are congruent.

The figure in pair 3 has also been rotated; this again preserves size and shape, so the figures are congruent.

The figure in pair 4 sees to have been reflected.  This did not change the size or shape of the figure, so the pair is congruent.

Nuetrik [128]
Kelly made a mistake by not following PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. She added 4 and 3 before multiplying it by two when the multiplication comes before the addition or subtraction. Brook is correct.
