Question

PLEASE HELP!!!!! △MNO is rotated about point A to △ M ′ N ′ O ′ . Which statements are true about the pre-image and image? Select each correct answer.

- ∠NOM≅ ∠N'O'M

- MN ≅ M'N>' < This one has a line on top of the letters.

-The image is the same size but a different shape than the pre-image.

-The image is the same shape but a different size than the pre-image.

Answer 1

△MNO is rotated about point N to △ M ′ N ′ O ′ .

⇒As you know that during Rotation the shape rotates by a certain angle, without changing it's shape and size.The two shapes i.e image and pre-image are congruent to each other.

Out of the options given :

- ∠NOM≅ ∠N'O'M [Two triangles are congruent]

- MN ≅ M'N [Sides are congruent]

is correct.
