Can you bisect yin and yang in this geometry brain teaser? You have a perfect yin yang symbol with a center point directly center with a semicircle on either side. You must bisect the areas of yin and yang (black and white) with a single straight line. This task is possible with a curved line, as well as a straight line. Do you know where the straight line would be positioned? This math problem may require knowledge of the area of a circle and more geometry knowledge.
