Geometric Analysis: Identifying Intersecting Lines in Multiple Diagrams

Question

Which figure(s) show intersecting lines?

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!

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.
