EXERCISE-5.4 IN ENGLISH | CHAPTER -5 | 6TH CLASS MATHS NCERT | NEW SYLLABUS 2024-25 Welcome to kishoriji classes. In this video we will be discussing CBSE class 6 Maths Chapter 5 Understanding Elementary Shapes Exercise 5.4 Full Solved 1. What is the measure of (i) a right angle? (ii) a straight angle? 2. Say True or False : (a) The measure of an acute angle (b) The measure of an obtuse angle (c) The measure of a reflex angle (d) The measure of one complete revolution = 360°. 3. Write down the measures of (a) some acute angles. (b) some obtuse angles. 4. Measure the angles given below using the Protractor and write down the measure. 5. Which angle has a large measure? First estimate and then measure. Measure of Angle A = Measure of Angle B = 6. From these two angles which has larger measure? Estimate and then confirm by measuring them. 7. Fill in the blanks with acute, obtuse, right or straight : (a) An angle whose measure is less than that of a right angle is______. (b) An angle whose measure is greater than that of a right angle is ______. (c) An angle whose measure is the sum of the measures of two right angles is _____. (d) When the sum of the measures of two angles is that of a right angle, then each one of them is ______. (e) When the sum of the measures of two angles is that of a straight angle and if one of them is acute then the other should be _______. 8. Find the measure of the angle shown in each figure. 9. Find the angle measure between the hands of the clock in each figure : 10. Investigate In the given figure, the angle measures 30°. Look at the same figure through a magnifying glass. Does the angle becomes larger? Does the size of the angle change? 11. Measure and classify each angle : ____
