When Arthur saw the triangle, his scalp began to tingle.
He was beginning to see why formation was so difficult to learn. But he was also beginning to understand some of the things he read in the textbook.
He thought to himself, "The expression has transformed from a single dimensional object into a two dimensional object all because of one additional point."
He mummured, "Just one more point!"
He was mummuring to himself when the lecturer pointed to the diagram of the triangle and said, "How many expressions are here?"
Without waiting for anyone to answer, he sneered and said, "If you think there are only three expressions here, you're deadly wrong."
"I meant what I said. Not only are you wrong, you're so wrong that it can get you killed."
He pointed to the triangle and said, "We now have three angles, three edges, a perimeter, and an area. That's eight different expressions. All because of the addition of a single more rule."
