A pole stands vertically inside a triangular park ABC. If the angle of elevation of the top of the pole from each corner of the park is the same, then the foot of the pole is at the:
Show Hint
Equal distances from vertices indicate the circumcentre.
Step 1:
Equal angles of elevation imply equal distances from the foot of the pole to the vertices.
Step 2:
The point equidistant from all vertices of a triangle is the circumcentre.
