Draw a line segment of length √8 cm.

Question

KnowledgeBoat · Accepted Answer

Steps of construction : 1. Draw a line segment XY. 2. Draw OB = 1 cm which is perpendicular to the line XY at O. 3. From B draw an arc of 3 cm cutting XY at A. 4. Join BA and OA. So, OAB is the right angle triangle. By pythagoras theorem, ⇒ AB² = OB² + OA² ⇒ 3² = 1² + OA² ⇒ OA² = 9 - 1 ⇒ OA² = 8 ⇒ OA = cm. Hence, OA is the required line of cm.
