Given ¯¯¯¯¯¯¯¯AB of length 3.9 cm, construct ¯¯¯¯¯¯¯¯PQ such that the length ¯¯¯¯¯¯¯¯PQ is twice that of AB . Verify by measurement.(Hint: Construct ¯¯¯¯¯¯¯¯¯PX such that length of ¯¯¯¯¯¯¯¯¯PX = length of ¯¯¯¯¯¯¯¯AB;then cut off ¯¯¯¯¯¯¯¯¯XQ such that ¯¯¯¯¯¯¯¯¯XQ also has the length of ¯¯¯¯¯¯¯¯AB.)

Given ¯¯¯¯¯¯¯¯AB of length 3.9 cm, construct ¯¯¯¯¯¯¯¯P

1.	Given ¯¯¯¯¯¯¯¯AB of length 3.9 cm, construct ¯¯¯¯¯¯¯¯PQ such that the length ¯¯¯¯¯¯¯¯PQ is twice that of AB . Verify by measurement.(Hint: Construct ¯¯¯¯¯¯¯¯¯PX such that length of ¯¯¯¯¯¯¯¯¯PX = length of ¯¯¯¯¯¯¯¯AB;then cut off ¯¯¯¯¯¯¯¯¯XQ such that ¯¯¯¯¯¯¯¯¯XQ also has the length of ¯¯¯¯¯¯¯¯AB.)
Answer» Given $¯ ¯¯¯¯¯¯ ¯ A B$ of length 3.9 cm, construct $¯ ¯¯¯¯¯¯ ¯ P Q$ such that the length $¯ ¯¯¯¯¯¯ ¯ P Q$ is twice that of AB . Verify by measurement. (Hint: Construct $¯ ¯¯¯¯¯¯¯ ¯ P X$ such that length of $¯ ¯¯¯¯¯¯¯ ¯ P X$ = length of $¯ ¯¯¯¯¯¯ ¯ A B$ ; then cut off $¯ ¯¯¯¯¯¯¯ ¯ X Q$ such that $¯ ¯¯¯¯¯¯¯ ¯ X Q$ also has the length of $¯ ¯¯¯¯¯¯ ¯ A B$ .)
