Distance between two points

Find the distance between A(16, 0, 8) and B(55, 0, -11).

Step-by-step solution

1. The distance is the true length of segment AB.
2. Work out the differences in X, Y and Z between the points.
3. Apply Pythagoras in space: d = √(ΔX² + ΔY² + ΔZ²).
4. Check the result: 43.38 units.

Result: 43.38 units.

If the points lie in the same projection plane, the distance is seen directly in that view; if not, it must be brought to true length.
