Q2: The minute hand of a clock moves from 12 to 3. What is the angle turned by the minute hand?
Sol: A full turn = 360°
From 12 to 3 = 1/4 of a full turn
Angle = 360° ÷ 4 = 90°

Q3: Anjali walked straight and then made a right turn. She then walked straight and made another right turn. How many degrees did she turn in total?
Sol: Each right turn = 90°
Total turn = 90° + 90° = 180°

Sol:  Half turn = 180°

Q6: Ravi was facing North. He turned clockwise to face East, then turned clockwise to face South. How many degrees did Ravi turn in total?
Sol: North → East = 90°
East → South = 90°
Total turn = 90° + 90° = 180°

Q8: A spinner moves from its starting point and completes one full turn. Then it moves another 1/2 turn. How many degrees did the spinner turn in total?
Sol: Full turn = 360°
Half turn = 180°
Total turn = 360° + 180° = 540°

FAQs on Important Questions: Angles as Turns - Mathematics (Maths Mela) Class 5 - New NCERT

1. What are angles and how are they measured in turns?
Ans. Angles are formed when two rays meet at a common endpoint called the vertex. They are measured in degrees, with a full turn or circle being 360 degrees. This means that if you make a complete turn, you've rotated through an angle of 360 degrees.
2. What is the relationship between degrees and turns?
Ans. The relationship between degrees and turns is straightforward: one complete turn is equal to 360 degrees. Therefore, if you turn halfway around, that would be 180 degrees, which is equivalent to a half turn. A quarter turn would be 90 degrees.
3. How can we use angles as turns in real-life situations?
Ans. Angles as turns can be observed in various real-life scenarios such as driving, where turning the steering wheel creates different angles. For example, a right turn often represents a 90-degree turn. Additionally, in sports like gymnastics or dance, athletes use angles in their movements to perform rotations and flips.
4. What are some common types of angles based on their turns?
Ans. Common types of angles based on their turns include acute angles (less than 90 degrees), right angles (exactly 90 degrees, representing a quarter turn), obtuse angles (greater than 90 degrees but less than 180 degrees), straight angles (exactly 180 degrees, representing a half turn), and reflex angles (greater than 180 degrees but less than 360 degrees).
5. How do you calculate the number of turns made by a given angle?
Ans. To calculate the number of turns made by a given angle, you can divide the angle in degrees by 360. For example, if you have an angle of 720 degrees, you would divide 720 by 360, which gives you 2 turns. This means the angle represents two complete rotations.
