use of angle of intersection of the two curves in daily life
Answers
Answer:
When two or more cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the of intersection.
Here, lines P and Q intersect at point O, which is the point of intersection.

In the given image below, there are many straight lines crossing each other and intersecting at the common point P.
intersecting at the common point
Properties of intersecting lines
The intersecting lines (two or more) meet only at one point always.
The intersecting lines can cross each other at any . This angle formed is always greater than 0o and less than 180o .
Two intersecting lines form a pair of vertical angles. The vertical angles are opposite angles with a common (which is the point of intersection).
Here, ∠a and ∠c are vertical angles and are equal. Also, ∠b and ∠d are vertical angles and equal to each other.
∠a + ∠d = straight angle = 180°

Crossroads: Two roads (consider as straight lines) meeting at a common point make crossroads.
Scissors: The two arms of the scissors form intersecting lines.
