Isosceles Triangle Step 1
Fold top left
corner until
top edge line
up along long
edge
Fold left
edge of
rectangle
to fit along
the sloping
edge.
Isosceles Triangle Step 2
Equilateral Triangle Step 1
Fold in half
lengthway
s and then
open out
again
Equilateral Triangle Step 2
Hold bottom right
corner;Fold bottom left corner to centre crease
Equilateral Triangle Step 3
Fold the
upper part so
that the left
edge lies
along the
sloping edge
Equilateral Triangle Step 4
Fold
small
triangle
over to
line up
with edge
f old top lef t corner until ‘top’ edge
lines up along right hand ‘long’ edge
Kite Step 1
f old bottom lef t corner onto the bottom of the triangle on the
right edge
Kite Step 2
f old lower right corner to the point shown
(edges should line up)
Kite Step 3
fl ip over and turn
round
Kite Step 4
f old in half , then
in half again, and
unfold
Rhombus Step 1
hold middle
right-hand point and fold the
bottom right-hand corner to the quarter line (stretching to
middle right-hand point)
repeat for the
top right-hand
corner
Rhombus Step 2
f old over ‘edge-to-edge’
(top fi rst;
then bottom)
