Class 5 Maths Chapter 3 Extra Questions – Angles as Turns Extra Questions Class 5

Question 1.
Ravi looked at the clock. After a quarter turn, where will the minute hand point?

Solution:
A quarter turn = 15 minutes = 3 numbers ahead on the clock.
So after a quarter turn, the minute hand will point to 11.

Question 2.
Write five objects make a exactly full turn?
Solution:
Clock’s minute hand (12 to 12) – Completes a full rotation every hour.
Ceiling fan blades – Rotate in full circles continuously.
Washing machine drum – Spins in full circles during the wash cycle.
Spinning top – Spins completely around multiple times.
Rotating chair (swivel chair) – Can turn in a full circle.
Mixer grinder blade – Spins fast in full circles.

Question 3.
What kind of angle is made by each turn (acute, obtuse, right)?
\(\frac{1}{4}\) turn, \(\frac{1}{6}\) turn, and \(\frac{1}{4}\) + \(\frac{1}{8}\) turn
Draw it to show your answer.
Solution:
Turning one-fourth of a circle, makes a right angle.

\(\frac{1}{6}\) turn means turning one-sixth of the circle which is less than \(\frac{1}{4}\) turn. So, this makes 4 an acute angle.

Since \(\frac{1}{4}\) turn makes a right angle and \(\frac{1}{8}\) turn make an acute angle. So, \(\frac{1}{4}\) + \(\frac{1}{8}\) turn make an obtuse angle.

Question 4.
Raghav is facing North. He turns 2 right angles clockwise, then 1 right angle clockwise, and then 2 right angles anti-clockwise. Which direction is he facing now?
Solution:
Raghav is facing North. He turns 2 right angles clockwise from North → South.

Now, he turns 1 right angle clockwise from South → West
Now, he turns 2 right angles anti-clockwise direction from West → East.
So, now he is facing East.
