Here is the link to the equilateral triangle calculator referenced in the video. If you remember your geometry, the interior angles of all triangles add up to 180. An equilateral triangle is a triangle in which all three sides are equal, so internal angles are 60° each. For our project, we wanted 6″ triangles so we cut our fabric at 6″ by the width of the fabric. Equilateral Triangle Calculator. Equation form: h = a√3: 2: a = 2h Equilateral triangle - a 3 sided geometrical figure that consists of 3 sides of equal length forming three internal angles of 60 degrees each. Enter the number of patches (same size, fabric, color) you wish to estimate fabric requirement for. The concepts are the same for other size triangles cut from the Hex N More , Sidekick and Super Sidekick rulers. www.play-crafts.com/blog/equilateral-triangle-quilt-calculator Once you can decipher a quilt block's grids, you can make it larger or smaller with ease.

How to Cut Triangles Using Your Cutting Mat. Example 1: If you are given altitude h and you want to calculate side a, then you need to use formula which connects h and a.. You don’t need any fancy rulers to cut triangles. For this tutorial I am going to show you how to sew 60-degree triangles together into pairs, then rows & then put the rows together. This calculator provides the calculation of all parameters of the triangle if you enter one of its parameters eg. This free online estimator tool will automatically deduct two inches from the usable fabric area to take into account fabric variability and trimming of the selvedges. Altitude of an equilateral triangle is the perpendicular drawn from the vertex of the triangle to the opposite side is calculated using Altitude=(sqrt(3)*Side)/2.To calculate Altitude of an equilateral triangle, you need Side (s).With our tool, you need to enter the respective value for Side and hit the calculate … Report abuse.
