Lines of symmetry of a kite

Step by step

The question

Question: how many lines of symmetry does a kite have?

1 Try the folds

Imagine folding the shape along a line.

If the two halves match exactly, it is a line of symmetry.

Fold along a diagonal.

The halves match: line 1.

Fold across the middle.

The corners do not meet.

It is not a line of symmetry.

2 Count the lines

We found 1.

So a kite has 1 line of symmetry.

Careful!

Only the fold through the top and bottom corners works.

Across the middle, the halves are not the same.

3 Check

Let's check.

Fold along line 1: this corner lands on that corner.

Every corner lands on a corner.

Right!

Let's look back.

First: try the folds.

Then: count the lines.

Last: check.
