A spaceship approaches Earth with a velocity V=0.65 c. A spaceship-based scientist determines that the area of a rectangle and of an equilateral triangle are equal. Consider that the two shapes are coplanar with respect to their orientation relative to V, as shown in the figure. Then, an Earth-based observer determines that the two areas are smaller than the areas determined by the scientist, with the rectangular area larger than the triangle.
