Question

The angle formed on a straight line is ___ (in degrees).

• A. 90
• B. 270
• C. 180
• D. 54

Answer 1

The correct option is C

180

We first draw a straight line, Let it be AB and mark a point on this line. Let this point be 'O'.

Now AB can be divided into two rays. They are AO and OB. The angle between AO and OB is ${180}^{\circ }$.

So, the angle formed on a straight line is ${180}^{\circ }$.
