Detailed Solution

The given statement is false.
Concept: Here, we apply the idea of angular measurement. Additionally, using the understanding that a magnifying glass enlarges an image seen through it, we may determine whether or not the angle is also enlarged.
A figure created by the intersection of two rays is called an angle, and it is quantified in radians or degrees. A magnifying glass is a tool with a convex lens used to enlarge or magnify the picture of an object placed beneath it.
The figure shows that the measured angle is

.
The figure remains unchanged but only enlarges in size when viewed via a magnifying glass since the entire image is amplified.
Question Image

When we use a magnifying glass, the entire image is magnified, shifting the entire image to a larger or greater axis, but the angle at which the ray strikes the point remains unchanged.
If we use the protractor (or D) to measure the angle, we can see that neither the angle's size nor its magnitude changes.
So, Neither, the angle does increase wider nor, the magnitude of the angle alters.
Hence, option 2 is correct.
