ESSENTIAL GUIDE Working with Equilateral Triangles

“Drawing, cutting and sewing equilateral triangles are useful skills for a patchworker, allowing you to feature them in a variety of exciting ways”

WHAT IS AN EQUILATERAL TRIANGLE?

An equilateral triangle is a shape that has three sides of equal length, with each angle being 60-degrees. This is different from a right-angled triangle that most patchworkers are used to, which has just two sides the same and two different angles – one of 90-degrees and two of 45-degrees. shows the two different triangles, with example measurements. You can see that in the equilateral triangle, the height is shorter than the width, which means that the overall shape is a square. A triangle can be created from a square, but it won’t be a mathematically ‘true’ equilateral triangle, so in this article we will
