Solution

In the above image $l_{1}, l_{2}, l_{3}$ are intersecting at a point. So $l_{1}, l_{2}$ are intersecting lines.

In the above image both $l_{1} and l_{2}$ are perpendicular to $l_{3}$ . So, $l_{1}, l_{2}$ are parallel to each other.

In the above image, given, $l_{2}, l_{3}, l_{4}$ are parallel and $l_{1} ⊥ l_{3}$ . So, $l_{1} ⊥ l_{2} and l_{1} ⊥ l_{4}$ .

In each case, match the image to the nature of the lines l1 and l2.

In the above image l1, l2, l3 are intersecting at a point. So l1, l2 are intersecting lines. In the above image both l1and l2 are perpendicular to l3. So, l1, l2 are parallel to each other. In the above image, given, l2, l3, l4 are parallel and l1⊥l3. So, l1⊥l2 and l1⊥l4.

In each case, match the image to the nature of the lines $l_{1}$ and $l_{2}$ .
