Q: Isn't it a little strange that we have so many words for different quadrilaterals, but not for different triangles? We got square, rhombus, rectangle.... "equilateral triangle" is a mouthful. I wonder if there are any languages that have a special word for that, or other types of triangle, like how the Inuit have tens of words for snow.
A: i can't find any languages that have a single word for equilateral triangle. however, most languages do have it for square. I think the reason boils down to the fact that in our 3-dimensional world, the dimensions are at 90° to each other. which is what makes the 'square' and 'cube' so essential in our languages
