obtuse angle in clock

With this in mind, we can say that each number represents an angle. The clock hands show a obtuse angle. Acute angles. Positive Angles: An angle that is rotated Counter Clock-wise or Anti clockwise is a positive angle. The second hand and the hour hand show an acute angle. The hour hand is three-fourths of the way from the "4" to the "5; that is, Angle =360-xHalf of clock is =180°And is distributed in 30°eachTherefore 5×30=150°Second angle = 360-150=210°Mark ia as brainlie… The hour hand has moved: 48 / 12 = 4 minutes after 2, which is 14 minutes from 12 O'clock. Angular speed of minute hand is 6 ° / minute. This problem is taken from the UKMT Mathematical Challenges . While practicing this, children will improve their concept on different types of angles (acute, right, obtuse, straight, reflex). At 4:45, the minute hand is at the "9" - that is, at the mark. Here student identifies type of angle formed by clock hands. On the little ends of the hands there are smaller angles. A clock takes the shape of a circle, which is composed of 360 degrees. That is clear. An example of an acute angle is below: Obtuse angles. Obtuse angles are angles that have a measure of more than 90° but less than 180°. For example, a capital letter "A" has an acute angle. Right angle and straight angle; Revolution in a clock; Acute, Obtuse, Reflex Angles Measuring angles; Measuring angles using protractor; Perpendicular Lines; Classifying triangles; Quadrilaterals; Polygons; 3 Dimensional Shapes Therefore, 34 minutes x 6 degrees =204 degrees. Acute angles are angles that have a measure of less than 90°. If you liked this problem, here is an NRICH task which challenges you to use similar mathematical ideas. For example, a clock showing 5 o'clock has an obtuse angle. There are 12 numbers on a clock that represent the hours. At 5 o'clockLet one angle=xSec. The measure of the angle between each number is given by . Students often approach the topic of angles by memorising lots of vocabulary (acute, obtuse, right angle, etc.) and ‘facts’ about angles around a point, on a straight line, inside and outside a triangle and other polygons and between a transversal and parallel lines. What is the obtuse angle between the hands of a clock at 6 minutes past 8 o'clock? Relative to hour hand , the angular speed of minute hand is 5.5 ° per minute. The angle measure between any two consecutive numbers on a clock is .. Angular speed of hour hand is 0.5°/minute. But each minute on the clock is 360 /60 =6 degrees . In the following image, AB and BC intersect to form an angle that is greater than 90° and less than 180°. Then they have to choose the appropriate rule to get the right answer to each calculation. Explanation: . The minute hand is at 48 minutes. Call the "12" point on the clock the zero-degree point. So, 48 - 14 =34 minutes, the angle between the two hands of the clock.
