Two campers on a beach by a lake want to determine the distance to a small island in the lake. They mark point A with a stake directly across from the island at point I, and walk perpendicular to to point B where they place another stake. Then they continue in a straight line to point C where they place another stake. Finally, they walk perpendicularly away from the lake to a point D such that points D, B, and I are on a line.

Are triangles AIB and CDB congruent? Are they similar? Explain your reasoning.

If AB = 300 feet, BC = 24 feet, and CD = 40 feet, what is the shortest distance
