Question

What is the first step in the construction of a line perpendicular to `stackrel(harr)(AB)` and passing through an external point M? Assume that the construction uses only a compass and a straightedge.

Answer 1

Explanation:

Answer 2

take your compass on a point on your line. then draw a circle. take the 2 points in which the circle hit the line and draw 2 circles larger than half the distance between he 2 points. take the point that they intersect and and connect it to the line and you point M and it is purpendicular. does that make sense?
