A spaceship approaches Earth with a velocity v = 0.65c. A spaceship-based scientist determines that the area of a circle and of an equilateral triangle are equal. Consider that the two shapes are coplanar with v; their orientation relative to v is shown in the figure. Then, the two areas as determined by an Earth-based observer are still equal to each other but smaller than the area determined by the scientist.
