The four shapes along the border are a kite, an arrow, an envelope and an arrowhead.

All four shapes are symmetrical. Each one has exactly 1 line of symmetry.

ShapeSymmetrical?Lines of symmetryWhere the line goes
KiteYes1Along the long stick, from the top corner to the tail
ArrowYes1Straight down the middle, through the tip
EnvelopeYes1Straight down the middle of the flap
ArrowheadYes1Straight 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.
