Answer 1

Step-by-step explanation:

Steps of Construction:

○ Draw a line of 2 cm,named it as OA

Draw a line of 2 cm,named it as OA○ At A draw a perpendicular line of 1 cm,let this line is AC.

Draw a line of 2 cm,named it as OA○ At A draw a perpendicular line of 1 cm,let this line is AC.○ Join OC, length of OC =√5 cm

Draw a line of 2 cm,named it as OA○ At A draw a perpendicular line of 1 cm,let this line is AC.○ Join OC, length of OC =√5 cm○ Take OC as base line ,and draw a perpendicular of 1 cm at C,let this is CD.
