Content

To draw simply means to inscribe or to make a mark.

Drawing involves making of marks or inscription or image on objects or surface in order to make a statement or pass on information or idea

Drawing is a universal language that is understood by almost everybody in the whole wide world

 

Drawing is a form of visual art in which a person uses various drawing instruments to mark paper or another two-dimensional medium. Instruments include graphite pencils, pen and ink, various kinds of paints, inked brushes, colored pencils, crayons, charcoal, chalk, pastels, various kinds of erasers, markers, styluses, and various metals (such as silver point). Digital drawing is the act of using a computer to draw. A drawing instrument releases a small amount of material onto a surface, leaving a visible mark. The most common support for drawing is paper, although other materials, such as cardboard, wood, plastic, leather, canvas, and board, may be used. Temporary drawings may be made on a blackboard or whiteboard or indeed almost anything. Drawing is a way of making marks to represent an object.

 

In basic Science and Technology, when we want to draw, we can make a representation on pieces of paper by making use of different types of drawing materials

It is very important to make use of drawing in science and Technology because it will give us a preview of whatever project we want to embark on and we can also make drawings to convey our ideas to others

SET SQUARE

It is used for drawing verticals and horizontal lines turned in different.

RULER

It is used for measuring distances between two or more points.

PROTECTOR

It is used for measuring angles.

T-SQUARE

It is used for drawing verticals and horizontal lines.
