Proposition: Prop. 11.11: Construction of Straight Line Perpendicular to Plane from point not on Plane
Euclid's Formulation
To draw a perpendicular straight line from a given raised point to a given plane.
* Let $A$ be the given raised point, and the given plane the reference (plane).
* So, it is required to draw a perpendicular straight line from point $A$ to the reference plane.
