Lines that Shape the World
I was watching Eli drawing on a large sheet of paper. With her little paws, Eli was drawing lines in different shapes, and I was fascinated.
I asked curiously, ”Hello, Eli! What are you drawing?” She replied, ”Hi, Riri! I’m working on a geometric drawing. I want to show you something about parallel and perpendicular lines. Would you like to learn about them?” I replied, excited, ”Yes, please!”
Eli paused for a moment and began to explain, “Parallel lines are lines that never meet, no matter how far they extend. Look here.” She traced two straight lines side by side, carefully keeping the same distance between them.
I asked, “Wow, so if I extend these lines, will they never touch?” “Exactly!” Eli replied. Then Eli smiled and said, “Let me show you perpendicular lines now. These lines meet at a right angle—90 degrees.” She drew a horizontal line and then a vertical one intersecting it.
“That’s interesting!” I exclaimed. “Do perpendicular lines always form corner shapes, like those in squares and rectangles?”
“That’s right,” Eli said, happy to see my curiosity. “You can see perpendicular lines in many places, like where a table’s legs meet its surface.” I looked around the workshop, trying to find examples of parallel and perpendicular lines.
Eli noticed my excitement. She said, “Look at the shelves. The edges of the shelves are parallel because they’re at the same height, and the sides of the shelves are perpendicular to the floor.” I studied the shelves closely. Suddenly, I realized parallel and perpendicular lines were everywhere!
Encouraged, I kept looking. Some objects were trickier. “What about the pattern on the rug? Are those lines parallel or perpendicular?”
“Eli smiled, “Look carefully. The horizontal lines are parallel, but the vertical ones are perpendicular to them. You’ve almost got it!”
Finally, I spotted a ladder leaning against the wall. “Wait…are the rungs parallel, and the sides of the ladder perpendicular to the floor?” “You got it!” Eli exclaimed. “Great observation, Riri. See? Once you start looking, the lines reveal themselves everywhere!”
Eli added, “Here’s a trick to remember. Think of ‘perpendicular’ as meaning a right angle, like a perfect corner. And parallel is like two friends walking side by side, never touching.”
I said, “That’s such a great way to remember! Parallel lines are like two roads that never cross, and perpendicular lines are like a road crossing at an intersection.” At that moment, I noticed even more examples in Eli’s drawings. It was exciting to see how these lines brought geometry to life in art!
I kept looking for more examples around the workshop. Every new discovery made me more confident about parallel and perpendicular lines. Eli smiled, “Lines are everywhere, Riri. Once you see them, you can create incredible designs and patterns.”
“I love this, Eli! Let’s draw something together!” I said, inspired. “Great idea, Riri!” Eli replied.
Together, we returned to the paper, ready to fill the page with a world of parallel and perpendicular lines, creating art full of imagination and joy.
