## FAQs on Examples: Measuring Angles Video Lecture - Mathematics (Maths) Class 6

 1. How do you measure angles using a protractor?
Ans. To measure an angle using a protractor, place the center of the protractor on the vertex of the angle. Align one side of the angle with the baseline of the protractor. Then, read the degree measure where the other side of the angle intersects the protractor scale.
 2. What is the difference between an acute angle and an obtuse angle?
Ans. An acute angle is an angle that measures less than 90 degrees, while an obtuse angle measures more than 90 degrees but less than 180 degrees. In simple terms, an acute angle is a smaller angle, while an obtuse angle is a larger angle.
 3. Can angles have decimal measurements?
Ans. Yes, angles can have decimal measurements. When using a protractor, the degree scale often includes decimal increments to allow for more precise angle measurements. For example, an angle may measure 45.5 degrees.
 4. What is the relationship between supplementary angles and linear pairs?
Ans. Supplementary angles are two angles that add up to 180 degrees, while a linear pair is a pair of adjacent angles that together form a straight line, measuring 180 degrees. Therefore, all linear pairs are supplementary angles, but not all supplementary angles are linear pairs.
 5. Are there any other methods to measure angles besides using a protractor?
Ans. Yes, there are alternative methods to measure angles. One method is using a digital angle finder, which uses electronic sensors to provide precise angle measurements. Another method is using trigonometric functions and measurements of sides in a right triangle to determine angle measures.
