Republic of South Africa

The flag of South Africa is composed of two equal horizontal bands of red and blue, with a yellow-edged black isosceles triangle superimposed on the hoist side of the field. This triangle has its base centered on the hoist end, spans about two-fifth the width and two-third the height of the field, and is enclosed on its sides by the arms of a white-edged green horizontally oriented Y-shaped band which extends along the boundary of the red and blue bands to the fly end of the field.
