The previous answer is just stupid. There are MANY times the clock makes 90 degree angles.
12:15, 12:45, 1:20, 1:50, 2:25, 2:55, 3:00, 3:30, 4:05, 4:35, 5:10, 5:40, 6:15, 6:45, 7:20, 7:50, 8:25, 8:55, 9:00, 9:30, 10:05, 10:35, 11:10, 11:40.
3:32 and 43 seconds
The angle in which the hands of the clock make at five o'clock is 150o.
A right angle which is 90 degrees
359 degrees......
make 120° when they are coplanar.
3:32 and 43 seconds
At 12:25, the hands of a clock make two angles, one of 137.5 degrees (an obtuse angle) and the other of 222.5 degrees.
The angle in which the hands of the clock make at five o'clock is 150o.
At 7 o'clock the hands on an analogue clock make a 210 degree angle - going from 12, clockwise, to 7.
In American Sign Language, the sign for "freedom" involves using both hands to form the letter "F" and moving them outward from the chest.
A right angle which is 90 degrees
Perpendicular lines make four 90 degree angles otherwise known as right angles.
An isosceles triangle consists of a 90 degree angle and two 45 degree angles
The two hands make an angle of 155 degrees (and 205 degrees).
359 degrees......
make 120° when they are coplanar.
Any two angles whose sum is equal to 90 degrees are called "complementary angles".
