FAQs on Infographics: Types of Angles - Mathematics for Class 6

1. What are the different types of angles?
Ans. The different types of angles are acute angles (less than 90°), right angles (exactly 90°), obtuse angles (greater than 90° but less than 180°), straight angles (exactly 180°), reflex angles (greater than 180° but less than 360°), and complete angles (exactly 360°).
2. How can I identify acute and obtuse angles?
Ans. An acute angle is one that measures less than 90 degrees, and you can identify it by observing that it looks sharp and narrow. An obtuse angle measures more than 90 degrees but less than 180 degrees, and it appears wider and more open compared to a right angle.
3. What is the importance of angles in daily life?
Ans. Angles are important in daily life because they are used in construction, art, navigation, and various sports. Understanding angles helps in designing buildings, creating artwork, and even in activities like playing basketball where angles determine the trajectory of the ball.
4. How do you measure angles using a protractor?
Ans. To measure angles using a protractor, place the midpoint of the protractor at the vertex of the angle. Align one side of the angle with the zero line of the protractor, then read the measurement on the scale where the other side of the angle intersects. Ensure you are using the correct scale (inner or outer) depending on the angle's orientation.
5. Can angles be classified based on their position?
Ans. Yes, angles can also be classified based on their position. For example, adjacent angles are two angles that share a common side and vertex but do not overlap. Complementary angles are two angles that add up to 90 degrees, while supplementary angles add up to 180 degrees.
