A drawing of a three-dimensional body related to 3 axes; the dimensions parallel to the axes are true to scale; one axis is usually vertical?

• A. Legend
• B. Landform Map
• C. Isopleths
• D. Isometric diagram

Answer: (D)

The drawing tests understanding of isometric projection, a way to represent a three-dimensional object on a two-dimensional plane where the dimensions along all three axes are shown to scale. In an isometric diagram, the three axes are drawn with equal scales, and typically one axis is vertical while the other two tilt equally to the sides. This setup preserves true measurements along each axis, so you can read the depth, width, and height directly from the drawing. That matches the description given: a 3D depiction with dimensions parallel to each axis true to scale and with one axis usually vertical. The other options refer to map features or data representations that don’t portray a 3D object with a true-scale, multi-axis projection.
