The different types of angles based on their measurements are: Acute Angle - An angle less than 90 degrees. These are complementary angles, supplementary angles, vertical angles, alternate interior angles, alternate exterior angles and corresponding angles. H = 10 M = 00 Calculate the Angle between 12 and the Hour hand 10: Since there are 360 degrees in a full circle (clock), and there are 12 hours, each hour represents 360/12 = 30 degrees So our formula is 30(H) So our formula is 30(10) θh = 300 Next, we know how each minute is 1/60 of an hour. So let's call that maybe a 128-degree angle. Each hour represents 30 degrees. For example 45.12°The small circle after the number means \"degrees\".
