Why is a compass called a compass?
The word “compass” means “to go around in a circular course,” since you can create a circle using a compass by going around in a circular motion on a sheet of paper this word fits the motion. The drawing compass has a needle on one end and a writing utensil of some sort, usually a pencil or lead, on the other end.
Is a protractor also called a compass?
The protractor and compass serve similar functions, but look very different. A protractor is either a circle or a semicircle. Compasses, which have also been around for centuries, consist of two legs on a hinge.
Which instrument is used to check the right angle?
Protractor
Why do protractors have two scales?
Measuring Angles The two scales make it easy for us to measure angles facing different ways. To measure the size of angle ABC, place the protractor over the angle so that the centre of the protractor is directly over the angle’s vertex, B; and the base line of the protractor is along the arm, BA, of the angle.
Do you read the top or bottom numbers on a protractor?
To measure an angle you put the rough side of the protractor down then put the vertex of the angle in the little hole in the middle, (shown on pages 3 and 4) and if the angle is acute you use the numbers on the bottom on the right but if it is acute but it is pointing to the left you use the left side and the top ( …
Where do you see angles in real life?
Where else can we find angles? Cloth-hangers, scissors, arrowhead, partly opened-doors, pyramids, Set squares, an edge of a ruler, an edge of tables, cycle spokes, wheels etc are examples of angles in real life. Different alphabets also form the examples of angles.
What is an example of an obtuse angle?
An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°. Examples of obtuse angles are: 100°, 120°, 140°, 160°, 170°, etc. ∠ PQR is an obtuse angle because it’s less than 180° and greater than 90°.
What is straight angle?
: an angle whose sides lie in opposite directions from the vertex in the same straight line and which equals two right angles.
