Answer
The four shapes along the border are a kite, an arrow, an envelope and an arrowhead.
The four shapes printed along the border of the page.
All four shapes are symmetrical. Each one has exactly 1 line of symmetry.
Shape
Symmetrical?
Lines of symmetry
Where the line goes
Kite
Yes
1
Along the long stick, from the top corner to the tail
Arrow
Yes
1
Straight down the middle, through the tip
Envelope
Yes
1
Straight down the middle of the flap
Arrowhead
Yes
1
Straight down the middle, through the point
The one line of symmetry of each shape, shown dashed.
Why it happens: Each shape is built the same way on the left and on the right of one middle line, so only that one fold makes the halves match.
Check it yourself: The kite’s tail in the picture is a wavy string. The tail by itself is not symmetrical — only the kite paper is. Trace just the kite and fold it to check.
