Answer: Option A. -> False
:
A
When visiting a new city or place, it would help to know the directions to guide us around. A map can be very useful. Itlets us know where we are and can also helpus identify directions that will help in navigating through a city.

Answer: Option C. -> Reflex angle
:
C
The angle shown in the figure is more than a straight angle of 180 degrees andless than a full circle of 360 degrees.
Hence, it is a reflex angle.

Answer: Option B. -> less than
:
B
A straight angle measures180°.
A reflex angle measures morethan a straight angle of 180°,but less than a full circle of 360°.
Hence, a straight angle is less than a reflex angle.

When two lines cross each other at a point we call them intersecting lines and the point where they meet is called the point of intersection.
Parallel lines never intersect each other.
Answer: Option C. -> obtuse
:
C
An angle which measures more than a right angle (90 degrees) and less than a straight angle (180 degrees) is called an obtuse angle.
Since 175 degrees is less than 180 degrees and greater than 90 degrees, it is an obtuse angle.

Answer: Option B. -> 2
:
B
A right angle is equal to 90 degrees.
A straight angle is equal to 180 degrees.
90×2=180
Hence, two right angles make a straight angle.

Answer: Option B. -> point
:
B
We can say that the study of geometry starts with a point. A point is an exact position in space. It is the basic unit of geometry. Any geometrical figure is a collection of infinite number of points.
