- Moira screamed and ran away from him, dropping several books and a protractor.
- To set the bridle provisionally, lay the kite face down and, with a protractor, arrange the division of the two halves of the bridle so that what will become the top leg is at approximately 75 degrees to the rear face of the kite.
- To measure the angle between the two lines we use a protractor.
- Note: Your protractor may well have another scale of numbers inside those shown in the picture.
- Two important rules when using a protractor are as follows.
- A protractor has been drawn on top of your map to show how it is used.
- 1 The centre cross of your protractor has to be over the corner of the angle.
- The vast unclouded duck-egg-blue semi-circle of sky, like a protractor on the horizon, was only broken by the occasional windmill or fringe of acid-yellow poplars or milk-green gum trees.
- Despite the fairly low success rates on questions probing the concepts, those questions asking pupils to use a protractor to measure given angles or draw an angle to a specified size yielded quite high success rates for both acute and obtuse angles.
- After calculating the angles for each, a protractor is required to draw these angles.
- Can construct accurately 2-D shapes with a ruler, protractor and compass The test results, described in Chapter 4 (pp. 41-;102), suggest that rectangular shapes can be drawn with good accuracy but they were not drawn with the use of geometrical instruments.
- Some possible criteria for this area of work are listed below: The pupil can: I name, draw or sort 2-D shapes; 2 name, draw or sort 2-D representations of 3-D shapes; 3 visualize 3-D shapes represented in 2-D; 4 construct accurately 2-D shapes with a ruler, protractor and compasses; 5 find the area and perimeter of a rectangular shape (whole units only); 6 find the volume of a 3-D cuboid given a 2-D representation; 7 compare and measure angles.
- 2 The base line of the protractor has to be on top of the bottom edge of the angle.
