FAQs on Examples: All Angles- 2 Video Lecture - Mathematics (Maths) Class 7 (Old NCERT)

1. What are the different types of angles?
Ans. There are several types of angles, including acute angles which measure less than 90 degrees, obtuse angles which measure more than 90 degrees but less than 180 degrees, right angles which measure exactly 90 degrees, and straight angles which measure exactly 180 degrees.
2. How do you identify a right angle?
Ans. A right angle can be identified by its measurement of exactly 90 degrees. It forms a perfect L shape, with one side perpendicular to the other.
3. What is the sum of complementary angles?
Ans. Complementary angles are two angles that add up to 90 degrees. Therefore, the sum of complementary angles is always 90 degrees.
4. What is the difference between a reflex angle and a full angle?
Ans. A reflex angle is an angle that measures more than 180 degrees but less than 360 degrees. On the other hand, a full angle measures exactly 360 degrees, forming a complete circle.
5. How do you classify an angle as acute, obtuse, or right without measuring it?
Ans. You can classify an angle without measuring it by observing its shape. If the angle forms a sharp corner, it is an acute angle. If it forms a wide corner, it is an obtuse angle. And if it forms a perfect L shape, it is a right angle.
