What is Pythagorean spiral?
A Pythagorean Spiral is a series of right triangles arranged in a spiral configuration such that the hypotenuse of one right triangle is a leg of the next right triangle.
How many types of spirals are there?
Spirals are classified by the mathematical relationship between the length r of the radius vector, and the vector angle q, which is made with the positive x axis. Some of the most common include the spiral of Archimedes, the logarithmic spiral, parabolic spiral, and the hyperbolic spiral.

How do you draw a square root spiral?
Ex 1.2, 4 – Chapter 1 Class 9 Number Systems (Term 1) Mark a center point O. From point O, draw a horizontal line OA of length 1 cm. 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. Join OC, here OC = √3.

Is a circle a spiral?
A spiral is a special curve in mathematics. This curve starts at a point, and then goes around the point, but gets farther and farther away from it. This is different from a circle (which is always at the same distance or an ellipse. A spiral is an “open” curve, unlike circles and ellipses which are closed curves.
