Title: Square Limit by M.C. Escher


1
Square Limit by M.C. Escher
  • How are the fish in the middle of the design and
    the surrounding fish alike?
  • How are they different?

2
Square Limit by M.C. Escher
  • Escher used a pattern of squares and triangles to
    create Square Limit.
  • These two triangles are similar.
  • Similar figures have the same shape but not
    necessarily the same size.

3
One way to create artwork with a smaller and
smaller framework is to base it on an isosceles
triangle with an apex angle whose measure divides
360º evenly.
4
We have elected to base our artwork on an
isosceles triangle with an apex angle of measure
45º where 360º/45º 8. An octagonal
configuration will result.
5
Select the midpoint of the base of the triangle.
6
Add a row of five similar smaller triangles by
drawing line segments parallel to the slant sides
of the triangle.

8
The result is the basis of the shrinking
repeating fundamental unit.
9
Add a continuous curve from vertex to vertex of
one of the sides of the original triangle.
10
Rotate this curve about the apex of the original
triangle to its congruent side.
11
Draw reductions of this curve from vertex to
vertex of each of the four reduced line segments
12
This is the shrinking tessellating unit.
13
Add interpreting interior features.

then add the tessellating unit with its
interpreting features and reductions thereof as
required.
