Creating the template by hand and not a computer means it can be challenging to make a perfect angular heart. If you are creating the template in a classroom, this is a good place to discuss how to create a perfectly symmetrical heart and how exact measurements are necessary to make perfect tessellations. Sorry 'bout that ( but you can see it in action in the video above.) (Somehow I forgot to take a photo of tracing the template. Our measurements were approximately 6 cm and 3 cm.Ĭut out the template on thin cardboard and trace a couple of practice tessellations to make sure your template is accurate. Be sure that the measurement of side of the heart is twice as long as one of the top "sides" or your tessellations will be off. We finally decided on an 80 degree angle, which we drew with our protractor. This took a bit of experimentation on our part to find the right angle for the bottom point of the heart.
