## FAQs on Examples: Construction of Angles Video Lecture - Class 6

 1. What are the different types of angles that can be constructed?
Ans. There are three types of angles that can be constructed: acute angles (less than 90 degrees), right angles (exactly 90 degrees), and obtuse angles (greater than 90 degrees but less than 180 degrees).
 2. How can I construct an acute angle of 45 degrees?
Ans. To construct an acute angle of 45 degrees, you can use a protractor. Start by drawing a line segment. Place the protractor on one end of the line segment with the center on the endpoint. Align the 45-degree mark on the protractor with the line segment. Finally, draw a line from the endpoint through the 45-degree mark.
 3. How do I construct a right angle of 90 degrees without using a protractor?
Ans. To construct a right angle of 90 degrees without a protractor, you can use a compass and a ruler. Start by drawing a line segment. Place the compass point on one end of the line segment and draw an arc that intersects the line segment. Without changing the compass width, place the compass point on the other end of the line segment and draw another arc that intersects the line segment. Finally, draw a line connecting the two intersection points, which forms a right angle.
 4. Can I construct an angle of 180 degrees? If yes, how?
Ans. No, it is not possible to construct an angle of 180 degrees. An angle of 180 degrees is a straight line, and a straight line cannot be constructed using basic geometric tools like a compass and a ruler.
 5. How can I construct an obtuse angle of 135 degrees?
Ans. To construct an obtuse angle of 135 degrees, you can use a protractor. Start by drawing a line segment. Place the protractor on one end of the line segment with the center on the endpoint. Align the 135-degree mark on the protractor with the line segment. Finally, draw a line from the endpoint through the 135-degree mark.
