Question

Investigate
In the given figure, the angle measure 30°.look at the same figure through a magnifying glass.Does the angle become larger ?Does the size of angle change?
​

Answer 1

it wont change because angle is just like percentage

Like in percentage full value or complete value is 100

do 20% increases when you look through a magnifying glass (investigate )

like that in angle a circle or 360° is full value
