A study says a triangle between the Vitruvian Man’s feet reveals a 1.64 ratio, also found in Bonwill’s jaw model and natural ...

Background. You'll be using Sketches 2, 3, and 4 of this file to explore which coloured triangles could fit into the given triangle outlines. Each triangle type has a different colour (pink for ...

This means that this triangle is equilateral. You can also describe the angles as congruent – they are exactly the same size. This triangle has 2 equal angles, each measuring 75º.

Since we know that the angle sum of a triangle is 180 degrees, we know that in equilateral triangles, all angles must be 60 degrees each. That is because 180 degrees divided by three angles is ...

You'll be using Sketch 1 of this file which has three different types of triangles - scalene, isosceles, equilateral. Each triangle type has a different colour (pink for scalene, red for equilateral, ...
