Longarm quilting machine. Quilting rulers are usually square or rectangular measuring instruments with length measurement and degree angle markings along multiple edges. Longarm quilting machines can be used to make larger quilts. Larger machines can be leveraged so that the quilter does not have to hold the fabric. [44]
T-square, or glazier's square, [1] or drywall square. [26] A T-square is a style of square where the blade is fixed onto on into the middle of the stock, forming a 'T' shape. The most common type of T-square is a guide for drawing horizontal lines on a drawing board, and can guide a set square to draw vertical or diagonal lines. [27]
Squaring the circle has been proved impossible, as it involves generating a transcendental number, that is, √ π. Only certain algebraic numbers can be constructed with ruler and compass alone, namely those constructed from the integers with a finite sequence of operations of addition, subtraction, multiplication, division, and taking square ...
A rotary cutter is a tool generally used by quilters to cut fabric.It consists of a handle with a circular blade that rotates, thus the tool's name. Rotary cutter blades are very sharp, can be resharpened, and are available in different sizes: usually smaller blades are used to cut small curves, while larger blades are used to cut to straight lines and broad curves.

It is composed of a rule and one or more interchangeable heads that can be attached to the rule. [1] [2] Other names for the tool include adjustable square, combo square, and sliding square.
Squaring of a quarter circle with radius 1. Squaring the circle with ruler and compass alone is impossible. However, if one allows the quadratrix of Hippias as an additional construction tool, the squaring of the circle becomes possible due to Dinostratus' theorem.
