Lines of symmetry

The Maths Habit

Which way does the dashed line go? Up and down, across or diagonal?

1across
2diagonal
3up and down

Fold each shape on the dashed line. Which one has two halves that match?

A
B
C

C. The two halves lie exactly on top of each other.

Line of symmetry
A fold line. One half lands exactly on the other.
Fold
Bend the shape over a line, like folding paper.
Diagonal
A slanting line from corner to corner.
