Question

You are given a line which is perpendicular to another straight line. Find the magnitude of the angle between those two lines in degrees.

Answer 1

A line is perpendicular to another line.


To measure the angle between the two lines we follow the below steps:

Step 1: Place the centre of the protractor at the intersection point of the lines.

Step 2: Measure the angle between the points where the lines touch the protractor's curve edge.


$\Rightarrow$ We observe that the angle subtended by two perpendicular line is ${90}^o$.
