00:03 Which lines cross each other?
00:06 When lines intersect, they split each other into two equal parts.
00:11 In this example, the lines intersect. Why? Because the segments are equal.
00:17 Here, the lines form a right angle. So, they are perpendicular.
00:21 But if segments aren't equal, they don't intersect.
00:26 In this case, the lines never meet, making them parallel.
00:31 Here, the lines intersect because the segments are equal.
00:35 And that's how we solve this question!

2

Step-by-step solution

Lines that intersect each other are lines that meet or cross each other.

The diagrams showing lines that cross each other are 1 and 3.

In diagram 2, the lines are perpendicular and vertical to each other, while in drawing 4, the lines are parallel to each other.
