It's entirely possible to draw a quadrilateral with 3 acute angles.
The fourth angle must be obtuse or reflex, but so what ? !

A straight line can intersect the side of a convex quadrilateral in at most two points and so divided it into at most two segments. A concave quadrilateral (an arrowhed or chevron) can be divided into three if the line touches the reflex vertex and cuts off the two "barbs" of the arrowhead. But 4 triangles is not possible.
It is a parallelogram.
