What type of angle is formed by a clock's hands when it is 3; 00

The correct answer is a right angle.

The angles on the clock make a 90 degree angle which is also known as a right angle.

Well you would have one hand on the 12 and one hand on the 3. now if you had a circle and cut it in to 4 equal pieces those are all 90 degree angles or a right angle. that is the same thing here.
