For private inquiries please write to [email protected]. Solution: Angle traced by hour hand in . The hour hand moves from one number to another in an hour, and since there are 12 numbers in total, we can divide 360: 12 = 30; so, the hour hand moves 30º in one hour. Kumon vs Smartick: Similarities and Differences, Parents often ask what are the main differences between Smartick and other more traditional, paper based methods (such as Kumon). © 2021 Smartick Intl. More specifically, we’ll see the kinds of angles that can be formed by the hands of a clock and how to calculate them. On a clock, we can see different kinds of angles based on its amplitude; void, acute, straight, obtuse, flat angles—even a full angle. We could use a protractor but, if we don’t have one handy, how can we calculate angles? In this first example, we can see that the angle formed by the hands is an acute angle because it’s less than 90° and more than 0°.

The acute angle is less than 90°, the right angle is equal to 90°, and the obtuse angle is greater than 90° but less than 180°, and the straight angle is exactly 180°. How to Label Angles. In our last example, we have a clock where the hands form a full angle, that is, an angle that’s 360°. The hour hand moves from one number to another in an hour, and since there are 12 numbers in total, we can divide 360: 12 = 30; so, the hour hand moves 30º in one hour. The minute hand makes a complete cycle, so it goes 360º. A clock is composed of 360 degrees and divided into 12 equal divisions. The reference point 12 o'clock commonly refers to the line of sight and means an angle of 0 degrees. An analog clock has 12 numbers, which divide the clock into 12 equal parts. The angle measure between any two consecutive numbers on a clock is. On a clock, we can see different kinds of angles based on its amplitude; void, acute, straight, obtuse, flat angles—even a full angle. hand in 20 min. If in one hour, which is 60 minutes, the hour hand moves 30°, it’ll move 0.5° in one minute, as we can see in the next picture.
