Twice.
Four right angles on a standard clock... I believe
24 right angles because in a hour it only does 1 right angle ,so in 24 hours there are going to be 24 right angles.

Three faces of clock hour ,minutes,
Two right angles. Between 2 and 8 there are 6 hours. The clock face [normally] shows 12 hours, so the hour hand moves 6/12 = 1/2 of a complete turn. 1/2 of a whole turn = 1/2 x 360o = 180o 1 right angle = 90o ⇒ 180o = 180o ÷ 90o right angles = 2 right angles
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.
3 o' clock 6 o'clock 9 o' clock 12 o'clock

The minute hand of a clock turns about 360 degrees each hour.
