3pm and 9pm are the two easy ones, but apparently there are loads more, try researching elsewhere on the internet
For 3:30 to be a right angle, the hour hand would point to the 3 and the minute hand would point to the 6. But the hour hand will be halfway between the 3 and the 4, hence not a right angle.Also, at 3:30 the angle of the hour hand would be at 105 degrees, the minute hand at 180, and the angular distance between both would be 75 degrees.
Eight times in a day the hands of a clock form straight angle. At first they form straight angle when the hour amd minute hand are on 3 and 9 in noon and night. Second, when the hour amd minute hand are on 9 and 3 in morning and night. Third when the hour amd minute hand are on 12 and 6 At last when the hour amd minute hand are on 6 and 12.
The hands form a right angle. At 3 o'clock, the minute hand points straight up, and the hour hand points straight to the right.
5.75 degrees.

straight angle
44 times. Starting at 12 o'clock, over the next 12 hours, the hour hand will make a 90o angle to the right (like quarter past) 11 times and 90o angle to the left (like quarter to) making a total of 22 times per 12 hours, or 44 per 24 hours aka 1 day.
It rotates 25*360 = 9000 degrees.
four times
24, or 48 if u count when they overlap
