Splitting angles with geometry nodes

[dan2 (dan)]

I want to visualize some basic math. I managed to get the equidistant point for 3 points of a triangle, the lines for the height of the triangle as well as splitting each side at the middle - I can’t figure out how to best split the angles though.

Basically I want 3 lines inside my triangle splitting the interior angles in half. Ideally it’d work in 3D. Any ideas?

how to best split the angles

Add the normalized edge vectors. It should point in the right direction:

Coincidentally, if you don’t normalize the edge vectors it’ll go through the mid-points.

works like a charm. thanks heaps!
