REFLECTIONS Reflections occur on the horizontal surfaces of bod ies of water, themirrored surfaces of glass. and the polished surfaces of floors. A reflecting surface presents an inverted or mirror image of the object being reflected. For example, if an object is resting directly on areflecting surface. the reflected image is adirect, inverted copy of the original. Thus, in a perspective view of the reflection, the reflected image follows the same perspect ive system of lines already established for the original image. Sightlines reflect off a mirrored surface at an angle equal to the angle of incidence. Each reflection therefore doubles t he apparent dimension of the space in a direction perpendicular to the mirrored surface. ( Anything in front of or above a reflecting surface appears at the same distance in back of or below the reflecting surface in adirection perpendicular to the surface. \ -- Oblique lines not parallel to the reflecting surface slant at an equal but opposit eangle in the reflection. 122 /ARCH ITECTURA l GRAPH ICS
