How to Represent √5 on the Number Line 📏 | Class 9 Maths | Easy Geometry Trick

📚 *Welcome to another exciting math concept!* In this video, we’ll show you *how to represent √5 (root 5) on the number line* using simple **geometric construction**. This is an important topic in **Class 9 Maths**, especially from the chapter **Number Systems**. Whether you're preparing for school exams or building your basic math skills, this video will make the concept of irrational numbers and their visualization on a number line **super easy and fun**! --- 🧮 *What You’ll Learn in This Video:* What is √5 and why it's an *irrational number* Step-by-step *geometric construction* of √5 on the number line Explanation with *Pythagoras Theorem* How to represent other square roots like √2, √3, etc. --- ✍️ *Construction Steps to Represent √5 on the Number Line:* 1. *Draw a number line* and mark a point O at 0 and A at 2 units to the right. 2. *Construct a perpendicular* at point A. 3. From A, measure 1 unit on the perpendicular and mark point B. 4. Join OB. Using a compass, place the pointer on O and draw an arc equal to the length OB. 5. Cut this arc on the number line. The point where the arc intersects the number line is **√5**. 📐 This method uses the **Pythagoras Theorem**, since OB² = OA² + AB² = 2² + 1² = 4 + 1 = 5, so OB = √5. --- 🧠 *Why This is Important:* Understanding how to place square roots like √5 on the number line helps visualize **irrational numbers**, a core concept in algebra and geometry. Mastering this will strengthen your **mathematical foundation**! --- 🏷️ *Tags (No Hashtags):* represent root 5 on number line root 5 on number line class 9 maths root 5 irrational numbers class 9 geometry root representation number system class 9 square root on number line sqrt 5 construction maths root number construction cbse class 9 math ncert number system root root 5 using pythagoras --- 🔖 *Hashtags:* #irrationalnumber #class9maths #mathsmadeeasy #IrrationalNumbers #mathconcepts #cbsemaths #MathsTutorial #ncertmathsclass11th #learnspark ---
