How do you make an equilateral triangle in easel?
In easel, click on the geometry icon in the upper left (square, circle, star, triangle). Select triangle and you will see some settings to the right. You want the height to be sqrt(3)/2 times the width. This is to say if the width is 1 inch, you want the height to be 0.8660254037844386 inches. From there, you can scale it as desired etc.
Thank you for your help
