Barney is in the triangular room shown here. He walks from a point on AC parallel to BC. When he reaches AB, he turns and walks parallel to AC. When he reaches BC, he turns and walks parallel to AB. How many times will Barney reach a wall before returning to his starting point?
Barney will reach a wall 5 times before returning to his starting point.
During my investigation I starting chose a starting point and chose parallel points until I returned to my original staring point. This was a very slow frustrating
