# Construct rectangle ABCD with the following data.

AB = 6 cm, AC = 7.2 cm.

Answer :

AB = 6 cm, AC = 7.2 cm

Construction:

1) Draw a line segment ‘**AB**’ of length ‘**6**’cm.

2) Draw a perpendicular line to ‘**AB**’ using Protractor at point ‘**B**’.

3) Now, taking ‘**A**’ as centre draw an arc of length ‘**7.2**’cm.

4) The arc will intersect the line at a point, this is the point ‘**C**’. Join the points ‘**A**’, ’**C**’ to form line segment ‘**AC**’ and ‘**B**’, ’**C**’ to form line segment ‘**BC**’.

5) Now draw perpendicular line to line segment ‘**BC**’ using protractor at point ‘**C**’.

6) Now draw perpendicular line to line segment ‘**AB**’ using protractor at point ‘**A**’.

7) These two perpendicular lines intersect at a point, this point is ‘**D**’

8) Join points ‘**A**’, ’**D**’ to form line segment ‘**AD**’ and points ‘**B**’, ’**D**’ to form line segment ‘**BD**’.

9) Thus Rectangle ‘**ABCD**’ is formed.
