#####Logarithmic Spiral, Golden Triangle, Golden Gnomon, Spira Mirabilis
A golden triangle is an isosceles triangle, where the longer sides and the short one has the golden ratio *ϕ= (sqrt(5)+1)/2*, and the three interior angles are 72°, 72°, and 36° , respectively. Starting from a golden triangle, one can construct inwards and/or outwards an infinite number of (similar) golden triangles, thus creating a logarithmic spiral. In the design, I have kept the triangles for children to ponder
