In 1 hour 2 times right angles are formed so in 24 hour it will be 48 times formed but 2 will be common.

Hey how many times do the clock hands form a 48 degree angle?
Babita pandey said:

I think the true answer is 48 because the min and the hour hand make 2 right angles in 1 hour. According to this they both made 48 right angles in 24 hours.

Hand of clock made 0 and 180 degrees 22 times in a day and every other degree 44 times.

Its not 8 o'clock and 2 o'clock its 1 o'clock and 2 o'clock that makes right angle one time. So it is 22 times for 12 hours. And 44 for 24 hours.

Generally for every 1 hr at two points it makes right angles.
But between 2:00 to 4:00 we get 3 right angles (approx 2:25, 3:00, 3:30) instead of 4 times.
Similarly between 8 and 10.
So we get 22 for 12 hrs and 44 for 24 hrs.

We know very well that both hands meet 11 times in 12 hours and therefor 22 times in 24 hours.
Considering process of meeting,
Both hands will be at right angle for 2 times per meeting.
So 22*2 = 44 times..!!
Simple as that.

How the two hands are in right angle two times an hour? Kindly help me.

For example let we consider 12 clock we have 2 right angles i.e. 12.15 and 12.45.
