Hello my wonderful Grade 5 superstar! 👋
I'm Kashef and today we're learning about Perpendicular Lines! These are lines that cross each other and make a perfect 90° angle — like the corners of a square or the letter "T". They are super important in buildings and design! Ready to meet the right-angle friends? Let’s go! 🚀
🧠 What Are Perpendicular Lines?
Two lines are perpendicular when they intersect (cross) and form a right angle (90°).
Symbol: ⊥
They make perfect square corners!
📍 Real-Life Perpendicular Lines
🪑 Corners of tables and chairs
📐 The letter "T" and "+" sign
🏠 Edges where walls meet the floor
📏 The x-axis and y-axis on graphs
🚦 Street signs and crosswalks
🎯 Spot the Perpendicular Lines!
1. Are the sides of a square perpendicular?
2. Which letter has perpendicular lines? (T, O, or S)
3. What is the special angle formed by perpendicular lines?
🔄 Perpendicular vs Parallel
Parallel lines → Never meet, stay same distance
Perpendicular lines → Meet at exactly 90°
