Answer:
E) Construction of a perpendicular to a line through a given external point.
Step-by-step explanation:
We are given an image representing some construction.
It can be seen that:
1. Arcs J and K are drawn from the point A on the line
2. From the points J and K, two bisecting arcs are joined.
After this, we will join the point A with the intersecting arcs.
This will give us a line perpendicular to the given line.
So, we have constructed a perpendicular to the given line through the point A, which is not on the given line.
So, last option is correct.
