	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.

If D is on AB, then angle ABD is zero degrees.  Do you mean angle ACD?
