Hello. I'm using the following code to generate an image of a triangle for a trigonometry quiz.
p = polygon2d([[0,0], [0,3], [4,0]], fill = False, axes = False)
p += text("$\theta$", (3, 0.2), fontsize = 22)
show(p)
The issue is that Sage doesn't seem to recognise $\theta$ as LaTeX, even though it's in dollar signs. In the corner of the triangle, it puts "heta". Why isn't this typesetting correctly? How can I fix it?
Thank you.
