Division of a Line Segment

In the given ...

Question

In the given image, segment AB has been divided in the ratio 3:2. This is done by
1. Draw any ray AX making acute angle with AB.
2. Draw a ray BY parallel to AX by making $∠ A B Y = ∠ B A X$
3. Locate the points $A_{1}, A_{2}, A_{3} . . . A_{3}$ on AX and $B_{1}, B_{2}$ on BY such that $A A_{1} = A_{1} A_{2} = B B_{1} = B_{1} B_{2}$
4. Join $A_{3} B_{2}$ by using which of the properties of parallel lines?

Solution

The correct option is B Alternate interior angles are equal

Here we use alternate interior angles are equal then the lin4es are parallel and $∠ X A B = ∠ A B Y$ as AX parallel to BY.
