When triangulating from the plan view, which two measurements are put on the true length diagram?

When triangulating from the plan view, the correct measurements to put on the true length diagram are plan length and elevation height. This is because triangulation involves creating a spatial relationship between the horizontal plan and the vertical elevation, allowing for accurate representation of dimensions in both planes.

In this method, the plan length represents the horizontal distance on the plan view, while the elevation height indicates how high this point rises in a vertical plane. Together, these two measurements help in accurately visualizing the three-dimensional shape of the component being fabricated, ensuring proper angles and dimensions align with both the horizontal and vertical representations on the drawing.

The other measurement combinations do not effectively represent the necessary dimensions for triangulation. For example, plan height and plan width would not account for the elevation, while elevation height and elevation length would not consider how the piece extends in the horizontal plane. Plan length and angle width focus more on angles without providing a complete picture of both dimensions needed for true length calculations.
