Road to a Point

A straight road and a row of houses are drawn on paper, with their lines slanting toward one tiny point on the horizon. Nearby houses are large, and the same houses farther away look smaller.

In the picture

  1. The vanishing point: the spot where road edges and rooflines meet on the horizon.
  2. The horizon line: the flat boundary where ground and sky meet at eye level.
  3. An orthogonal: a road edge that slants from the foreground toward the vanishing point.
  4. The nearest house: the largest of four identical houses, showing how size shrinks with distance.

Examples

  • A railway track seen from a train seems to narrow to a point in the distance.
  • A school corridor looks narrower as it reaches the far wall.

Quiz: Road to a Point (Age 13)

  1. When lines recede into depth, where do they appear to meet?

    • At many separate points on the ground
    • At one point on the horizon
    • At the nearest edge of the drawing
  2. What is an orthogonal in a drawing that shows depth?

    • The largest object in the foreground
    • The flat boundary where ground and sky meet at eye level
    • A line that slants from the foreground toward the vanishing point
  3. How do objects of the same size appear as they get farther away?

    • They look smaller
    • They look larger
    • They stay exactly the same apparent size
