- In geometry, the spiral of Theodorus (also called square root spiral, Einstein spiral or Pythagorean spiral) is a spiral composed of right triangles, placed edge-to-edge. It was named after Theodorus of Cyrene Construction. The spiral is started with an isosceles right triangle, with each leg having.
- Sep 05, 2020 From point A, draw a perpendicular line AB of length 1 cm. Join OB, here OB = √2. Now, from point B, draw a line perpendicular to OB (Use set squares) of length 1 cm. Mark the end point as C. Join OC, here OC = √3. Repeat steps 4, 5, 6 for √4, √4, √4. Our square root spiral is ready. Check out the video below.
- Straightedge and compass construction, also known as ruler-and-compass construction or classical construction, is the construction of lengths, angles, and other geometric figures using only an idealized ruler and compass. The idealized ruler, known as a straightedge, is assumed to be infinite in length, have only one edge, and no markings on it.
Constructing The “Seed of Life” pattern- a classic geometric construction
With only a compass, one may contstruct this primal form. Starting with a circle, center the next one on the edge and then use each new intersection as the next center.
Background info about the Seed of Life pattern
(An excerpt from page 15 of Sacred Geometry Design Sourcebook.)
Built well over three thousand years ago, the temple of the Osirion at Abydos, Egypt contains huge monolithic rectangular columns unlike those found anywhere else in Egypt; the columns are arranged within a rectangular plan which is derived from a mirrored pentagon/double circumscribed circle pattern. Indelibly etched, high on one of these monolithic columns are patterns that have come to be known as the Seed of Life and Flower of Life patterns. These patterns contain a vast system of information about life itself, including templates for the five Platonic Solids, which in turn, contain the Pi, square root of 2, square root of 3 and Phi proportions and much more.

Square and Square Root Construction by Compass and Straightedge. Given the unit length, and the segment of length construct. Solution: Let be the right angle triangle with. Let the axis of the side meets the line in point. Construct the semicircle with center in and radius.
Did you draw the Seed of Life pattern with your compass in school but not know it had a name? This pattern is probably the most intuitive thing to make with a compass, and, as the simplest things often are, it is probably one of the most profound geometries.
To construct the Seed of Life pattern:
1) Fix your compass to the size desired for the center circle and make a circle.
2) Move the pivot point of the compass to the edge of the center circle and make another circle. (This creates the familiar “eye” archetype of the vesica piscis shape which sybolizes communion, relationship and much more.)
3) Move the pivot point of the compass to the edge of the center circle where the first two circles intersect and make the next circle.
4) Move the pivot point of the compass to the edge of the center circle where the center and third circles intersect and make the next circle.
5) Move the pivot point of the compass to the edge of the center circle where the center and fourth circles intersect and make the next circle.
6) Move the pivot point of the compass to the edge of the center circle where the center and fifth circles intersect and make the next circle.
7) Move the pivot point of the compass to the edge of the center circle where the center and sixth circles intersect and make the next circle.
That does it! You’ve just constructed the classic “Seed of Life” pattern, following the ancient tradition of geometers going back into antiquity.

Here’s the math involved (for those interested):
The vesica piscis shape is made with each new added circle; the square root of 3 (approx. 1.732) is the proportion of this shape which is also the ratio of the diagonal of a cube to one of its edges.
