Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What does it mean for two shapes to be matching or twin shapes?Matching shapes have sides and corners that line up exactly. When you pair each corner of one shape with a corner of the other, the sides between them also line up in the same order.
2. How do we know if two polygons are the same size and shape?Two polygons are the same size and shape when every pair of corresponding sides has the same length and every pair of corresponding angles has the same measure.

Bijective Mapping: A one-to-one correspondence where each element in one set pairs with exactly one element in another set.
Isometry: A geometric transformation that preserves distances, such as translation, rotation, or reflection.
Scale Factor: The constant ratio between the lengths of corresponding sides of two similar geometric figures.
