Create a circle centered at point A with a radius large enough for you to distinguish the two points where the circle intersects the two legs of ∠BAC. Label the points where the circle intersects ∠BAC as D and E.
Create two circles centered at points D and E with equal radii that are long enough to allow the circles to intersect.
There are two points where the circles intersect each other. Mark the point that is farthest from the vertex, and label it F.
