Definition: The boundary line of a surface.
Alright class, settle down and let’s take a look! That’s a really good definition you found in the dictionary – “The boundary line of a surface.” But let’s break that down with a little rhyme to make it stick. “Edges” simply mean where things end , A border, a line, my friend! Like a book's cover, neat and bright, Or a mountain's slope in morning light. Think about a piece of paper, crisp and new, The edge is the line it holds for you. Or a river flowing, carving its way, Edges define where water plays! It’s not inside – that’s the core, But right around , wanting more. So, "edges" represent those outer lines, the limits we see, of anything shaped and defined. Do you understand? Any questions before we move on to the next concept?
