[zzbxmqdl] Octagonal triangle

The isosceles triangle that is 1/8 of a regular octagon looks nice.  As a tile, what interesting patterns or figures can be built with it?

With a square, truncated square tiling.

Cute puzzle: 3 regular polygons share a vertex, together covering the entire 360 degrees around the vertex. What is the largest number of sides any of the polygons can have?
