which way is horizontal direction
Question: Which way is horizontal? Which way is horizontal is a common question. Horizontal is left to right or east to west, or flat on the surface. Many people remember it by thinking about looking out over the horizon, which is flat, or goes from side to side, and horizon sounds like horizontal. Others look at the first letter H, and see how it has a line on either side indicating start and stop point, and then a flat line in between.
