Tiling a Chamfered Rectangle with a Polyabolo

Introduction

A polyabolo or polytan is a plane figure formed by joining equal isosceles right triangles at their legs or hypotenuses. Here are some polyaboloes:

A chamfered rectangle is a rectangular polyabolo with its corner cells clipped diagonally. To prevent cuts from meeting, I require the dimensions of the rectangle to be 3 or greater.

Here I show the minimal known chamfered rectangle that can be tiled by each polyabolo.
