Here's another problem I heard as a 9th grader. If somebody
solved it in 5 minutes, please let me know. I didn't, and neither di
my teacher, friends, cousins and others who were shown the problem.
Given an isocele triangle ABC with A = 20 degrees, B = C = 80 deg.
On AB take a point D such that AD = BC. Find the angle ABD.

Obviously, the angle ABD (took 30 seconds or so) is 0 degrees, (or if
you prefer, 360 degrees)
Right?? If not, where did I go wrong? All I did was draw the problem as
stated and look at it..............
