The number √2 is shown on a number line. Steps are given to show √3 on the number line using √2. Fill in the boxes properly and complete the activity. The point Q on the number line shows the number ………. A line perpendicular to the number line is drawn through the point Q. Point R is at unit distance from Q on the line. Right angled ∆OQR is obtained by drawing seg OR. l(OQ) = √2, l(QR) = 1 ∴By Pythagoras theorem, [l(OR)]² = [l(OQ)]² + [l(QR)]² Draw an arc with centre O and radius OR. Mark the point of intersection of the line and the arc as C. The point C shows the number √3 Question 2. Show the number √5 on the number line. Question 3. Show the number √7 on the number line.
